पर्यावरण निबंध 1 (100 शब्द)

वातावरण एक प्राकृतिक परिवेश है जो पृथ्वी नामक इस ग्रह पर जीवन को विकसित, पोषित और नष्ट होने में मदद करता है। प्राकृतिक वातावरण पृथ्वी पर जीवन के अस्तित्व में एक बड़ी भूमिका निभाता है और यह मनुष्यों, पशुओं और अन्य जीवित चीजो को बढ़ने और स्वाभाविक रूप से विकसित होने में मदद करता है। लेकिन मनुष्य के कुछ बुरे और स्वार्थी गतिविधियों के कारण हमारा पर्यावरण प्रभावित हो रहा है। यह एक महत्वपूर्ण विषय है और हर किसी को हमारे पर्यावरण को कैसे बचाया जाये और इसे सुरक्षित रखने के बारे में जानना चाहिए ताकि इस ग्रह पर जीवन के अस्तित्व को जारी रखने के लिए प्रकृति का संतुलन सुनिश्चित हो सके|

पर्यावरण निबंध 2 (150 शब्द)

जैसा की हम सब लोग पर्यावरण से भली भाति परिचित है, पर्यावरण वह है जो प्रकिृतिक रूप से हमारे चारो तरफ है और पृथ्वी पर हमारे दैनिक जीवन को प्रभावित करता है। जो हवा हम हर पल सांस लेते है, पानी जो हम अपनी दिनचर्या में इस्तेमाल करते है, पौधें, जानवर और अन्य जीवित चीजे यह सब पर्यावरण के तहत आता है। जब प्राकृतिक चक्र किसी भी गड़बड़ी के बिना साथ साथ चलता रहे तब एक पर्यावरण स्वस्थ वातावरण कहा जाता है| प्रकृति के संतुलन में किसी भी प्रकार का बाधा वातावरण को पूरी तरह प्रभावित करता है जो की मानव जीवन का नाश कर देता है|

इंसान की उन्नत जीवन स्तर के युग में, वायु प्रदूषण, ध्वनि प्रदूषण, वनों की कटाई, जल प्रदूषण, मिट्टी प्रदूषण, अम्ल वर्षा और तकनीकी प्रगति के माध्यम से मनुष्यो द्वारा किये गए अन्य खतरनाक आपदाओं के रूप में हमारा प्रदुषण काफी हद तक प्रभावित हो रहा है| हम सभी को हमारे प्राकृतिक पर्यावरण की रक्षा के लिए और इसे सामान्य रूप से सुरक्षित रखने के लिए एक साथ शपथ लेनी चाहिए।

पर्यावरण निबंध 3 (250 शब्द)

पर्यावरण का मतलब है सभी प्राकृतिक परिवेश जैसे की भूमि, वायु, जल, पौधें, पशु, ठोस सामग्री, कचरा, धूप, जंगल और अन्य वस्तु। स्वस्थ वातावरण प्रकृति के संतुलन को बनाए रखता है और साथ ही साथ पृथ्वी पर सभी जीवित चीजों को बढ़ने, पोषित और विकसित करने में मदद करता है। हालांकि अब कुछ तकनीकी उन्नति परिणाम स्वरुप मानव निर्मित चीजे वातावरण को कई प्रकार से विकृत कर रहीं हैं जोकि अंततः प्रकृति के संतुलन को बिगाड़ रही है। हम अपने जीवन को साथ ही साथ इस ग्रह पर भविष्य में जीवन के अस्तित्व को खतरे में डाल रहे हैं|

यदि हम प्रकृति के अनुशासन के खिलाफ गलत तरीके से कुछ भी करते हैं तो ये पूरे वातावरण के माहौल जैसे की वायु-मंडल, जलमंडल और स्थलमंडल को अस्तव्यस्त करती है। प्राकृतिक वातावरण के अलावा, मानव निर्मित वातावरण भी मौजूद है जो की प्रौद्योगिकी, काम के माहौल, सौंदर्यशास्त्र, परिवहन, आवास, सुविधाएं और शहरीकरण के साथ सम्बंधित है| मानव निर्मित वातावरण काफी हद तक प्राकृतिक वातावरण को प्रभावित करता है जिसे हम सभी एकजुट होकर बचा सकते हैं|

प्राकृतिक वातावरण के घटक संसाधन के रूप में उपयोग किया जाता है हालाँकि कुछ बुनियादी भौतिक जरूरतों और जीवन के उद्देश्य को पूरा करने के लिए इंसान द्वारा इसका शोषण किया जाता है| हमें हमारे प्राकृतिक संसाधनों को चुनौती नहीं देनी चाहिए और पर्यावरण में इतना प्रदूषण या अपशिष्ट डालने में रोक लगानी चाहिए। हमें अपने प्राकृतिक संसाधनों को महत्व देना चाहिए और प्राकृतिक अनुशासन के तहत उन्हें इस्तेमाल करना चाहिए।

हमें कई प्रकार से मदद करने के लिए वातावरण में हमारे आस पास की सभी प्राकृतिक संसाधन शामिल है| यह हमें आगे बढ़ने और विकास करने के लिए बेहतर माध्यम प्रदान करता है। यह हमें इस ग्रह पर जीवन जीने के लिए सभी चीजे देता है। हालांकि, हमारे वातावरण को भी ये जैसा है वैसे ही बनाये रखने के लिए हम सब की मदद की जरुरत होती है, ताकि ये हमारे जीवन को पोषण दे सके और हमारे जीवन को बर्बाद न करे। मानव निर्मित प्रौद्योगिकीय आपदा की वजह से हमारे पर्यावरण के तत्वों में दिन ब दिन गिरावट आ रही है।

सिर्फ पृथ्वी ही एक ऐसी जगह जहा पर ही पुरे ब्रह्मांड में जीवन संभव है, और पृथ्वी पर जीवन जारी रखने के लिए हमें हमारे पर्यावरण की मौलिकता को बनाए रखने की जरूरत है| विश्व पर्यावरण दिवस एक अभियान है जो कई वर्षो से हर साल 5 जून को पूरे विश्व में पर्यावरण सुरक्षा और सफाई के लिए जनता में जागरूकता का प्रसार करने के लिए मनाया जाता है। हम अपने पर्यावरण को बचाने के तरीके और सभी बुरी आदतें जो की हमारे पर्यावरण को दिन ब दिन नुकसान पंहुचा रहा है के बारे में जानने के लिए हमें इस अभियान में भाग लेना चाहिए|

हम पृथ्वी के हर व्यक्ति के द्वारा उठाए गए छोटे कदम से बहुत ही आसान तरीके से हमारे पर्यावरण को बचा सकते हैं जैसे की; कचरे की मात्रा कम करना, कचरे को ठीक से उसकी जगह पर फेकना, पोली बैग का इस्तेमाल बंद करना, पुराने वस्तुओं को नए तरीके से पुन: उपयोग में लाना, टूटी हुई चीजों का मरम्मत करना और पुन: उपयोग में लाना, रिचार्जेबल बैटरी या अक्षय एल्कलाइन बैटरी का उपयोग करना, फ्लोरोसेंट प्रकाश का प्रयोग करना चाहिए, वर्षा जल संरक्षण करना, पानी की बर्बादी को कम करना, ऊर्जा संरक्षण करना, और बिजली का कम से कम उपयोग इत्यादि|

पर्यावरण निबंध 5 (400 शब्द)

पर्यावरण पृथ्वी पर जीवन के पोषण के लिए प्रकृति द्वारा भेंट दी गयी है। वह हर चीज जो हम अपने जीवन जीने के लिए इस्तेमाल करते है वो पर्यावरण के अंतर्गत आता है जैसे की पानी, हवा, सूरज की रोशनी, भूमि, पौंधें, जानवर, जंगल और अन्य प्राकृतिक चीजें। हमारा पर्यावरण पृथ्वी पर स्वस्थ जीवन का अस्तित्व बनाये रखने में एक बहुत महत्वपूर्ण भूमिका निभाता है। हालांकि, आधुनिक युग में हमारा पर्यावरण मानव निर्मित तकनीकी उन्नति के कारण दिन ब दिन बद्तर होती जा रही है। इस प्रकार, पर्यावरण प्रदूषण सबसे बड़ी समस्या बन गयी है जिसका हम आज सामना कर रहे हैं।

पर्यावरण प्रदूषण हमारे जीवन के विभिन्न पहलुओं जैसे की सामाजिक, शारीरिक, आर्थिक, भावनात्मक और बौद्धिक को नकारात्मक रूप से प्रभावित कर रहा है। पर्यावरण का दूषितकरण कई रोगों को लाता है जिससे इंसान पूरी जिंदगी पीड़ित हो सकता है। यह किसी समुदाय या शहर की समस्या नहीं है, बल्कि ये पुरे दुनिया की समस्या है जो की किसी एक के प्रयास से खत्म नहीं हो सकता। अगर इसका ठीक से निवारण नहीं हुआ तो ये एक दिन जीवन का अस्तित्व खत्म कर सकता है। हर आम नागरिक को सरकार द्वारा शुरू की गयी पर्यावरण सुरक्षा कार्यक्रम में भाग लेना चाहिए।

हमें हमारे पर्यावरण को स्वस्थ्य और प्रदुषण से दूर रखने के लिए अपने स्वार्थ और गलतियों को सुधारना होगा। यह विश्वास करना मुश्किल है, लेकिन सच है की हर किसी द्वारा केवल एक छोटे से सकारात्मक आंदोलनों की वजह से बिगड़ते पर्यावरण में बड़ा बदलाव लाया जा सकता है। वायु और जल प्रदूषण विभिन्न बीमारियों और विकारों द्वारा हमारे स्वास्थ्य को खतरे में डाल रहे हैं। आज कल हम किसी भी चीज को सेहतमंद नहीं कह सकते क्योकि जो हम खाते है वो पहले से ही कृत्रिम उर्वरकों के दुष्प्रभाव से प्रभावित हो चूका है और हमारे शरीर को रोगों से लड़ने की छमता को कमजोर कर दिया है| यही कारण है कि हम में से कोई भी स्वस्थ और खुश रहने के बावजूद कभी भी रोगग्रस्त हो सकता है।

अतः यह दुनिया भर के लिए गंभीर मुद्दा है जो हर किसी के निरंतर प्रयासों से हल होना चाहिए। हमें विश्व पर्यावरण दिवस में भाग लेना चाहिए ताकि हम सक्रिय रूप से पर्यावरण सुरक्षा कार्यो में भाग ले सके|


 

पर्यावरण निबंध 6 (500 शब्द)

वो सभी प्राकृतिक चीजें जो पृथ्वी पर जीवन संभव बनाती है पर्यावरण के अंतरगर्त आती है जैसे की जल, वायु, सूर्य के प्रकाश, भूमि, अग्नि, वन, पशु, पौंधें, इत्यादि| ऐसा माना जाता है की केवल पृथ्वी ही पुरे ब्रह्माण्ड में एक मात्र ऐसा गृह है जहा जीवन के अस्तित्व के लिए आवश्यक पर्यावरण है| पर्यावरण के बिना यहाँ हम जीवन का अनुमान नहीं लगा सकते इसीलिए हमें भविष्य में जीवन की संभावना सुनिश्चित करने के लिए अपने पर्यावरण को स्वस्थ्य और सुरछित रखना चाहिए| यह पृथ्वी पर रहने वाले प्रत्येक व्यक्ति की जिम्मेदारी है| हर किसी को आगे आना चाहिए और पर्यावरण की सुरक्षा के अभियान में शामिल होना चाहिए।

प्रकृति का संतुलन बनाए रखने के लिए पर्यावरण और जीवित चीजो के बीच नियमित रूप से विभिन्न चक्र घटित होते रहते है। हालांकि, अगर किसी भी कारण से ये चक्र बिगड़ जाते हैं तो प्रकृति का भी संतुलन बिगड़ जाता है जो की अंततः मानव जीवन को प्रभावित करता है। हमारा पर्यावरण हजारो वर्षो से हमें और अन्य प्रकार के जीवो को धरती पर बढ़ने, विकसित होने और पनपने में मदद कर रहा है। मनुष्य पृथ्वी पर प्रकृति द्वारा बनाई गई सबसे बुद्धिमान प्राणी के रूप में माना जाता है इसीलिए उनमे ब्रह्मांड के बारे में पता करने की उत्सुकता बहोत ज्यादा है जोकि उन्हें तकनीकी उन्नति की दिशा में ले जाता है।

हर व्यक्ति के जीवन में इस प्रकार की तकनीकी उन्नति दिन-ब-दिन पृथ्वी पर जीवन के संभावनाओं को खतरे में डाल रहा है क्योकि हमारा पर्यावरण धीरे-धीरे नष्ट हो रहा है| ऐसा लगता है की ये एक दिन जीवन के लिए बहोत हानिकारक हो जाएगी क्योकि प्राकृतिक हवा, मिट्टी और पानी प्रदूषित होते जा रहे हैं| हालाँकि यह इंसान, पशु, पौधे और अन्य जीवित चीजों के स्वास्थ्य पर बुरा प्रभाव दिखाना शुरू कर दिया है। हानिकारक रसायनों के उपयोग द्वारा कृत्रिम रूप से तैयार उर्वरक जो की मिट्टी को खराब कर रहे हैं परोक्ष रूप से हमारे दैनिक खाना खाने के माध्यम से हमारे शरीर में एकत्र हो रहे हैं। औद्योगिक कंपनियों से उत्पन्न हानिकारक धुँआ दैनिक आधार पर प्राकृतिक हवा को प्रदूषित कर रहे हैं जो की काफी हद तक हमारे स्वास्थ्य को प्रभावित कर रहे हैं क्योकि इसे हम हर पल साँस लेते हैं|

इस व्यस्त, भीड़ और उन्नत जीवन में हमे दैनिक आधार पर छोटी छोटी बुरी आदतों का ख्याल रखना चाहिए। यह सत्य है की हर किसी के छोटे से छोटे प्रयास से हम हमारे बिगड़ते पर्यावरण की दिशा में एक बड़ा सकारात्मक बदलाव ला सकते हैं। हम हमारे स्वार्थ के लिए और हमारे विनाशकारी इच्छाओं को पूरा करने के लिए प्राकृतिक संसाधनों का गलत उपयोग नहीं करना चाहिए। हम हमारे जीवन को बेहतर बनाने के लिए विज्ञान और प्रौद्योगिकी विकास करना चाहिए लेकिन हमेशा यह सुनिश्चित रहे की भविष्य में हमारे पर्यावरण को इससे कोई नुकसान न हो। हमें सुनिश्चित होना चाहिए की नई तकनीक हमारे पारिस्थितिकी संतुलन को कभी गड़बड़ न करे|

This article is about the cat. For other uses, see Snow Leopard (disambiguation).

The snow leopard or ounce (Panthera uncia) is a large cat native to the mountain ranges of Central and South Asia. It is listed as Vulnerable on the IUCN Red List of Threatened Species because the global population is estimated to number less than 10,000 mature individuals and decline about 10% in the next 23 years. As of 2016, the global population was estimated at 4,500 to 8,745 mature individuals.[1][3]

The snow leopard inhabits alpine and subalpine zones at elevations from 3,000 to 4,500 m (9,800 to 14,800 ft), ranging from western Afghanistan to Mongolia and western China. In the northern range countries, it also occurs at lower elevations.[4][5]

Taxonomically, the snow leopard was initially classified in the monotypic genusUncia.[2] Since 2008, it is considered a member of the genus Panthera based on results of genetic studies. Two subspecies were described based on morphological differences, but genetic differences between the two have not been confirmed.[1] It is therefore regarded a monotypic species.[6]

Naming and etymology

Both the latinized genus name, Uncia, and the occasional English name ounce are derived from the Old Frenchonce, originally used for the European lynx. Once itself is believed to have arisen by back-formation from an earlier variant of lynx, lonce – the "l" of lonce was construed as an abbreviated la ('the'), leaving once to be perceived as the animal's name. This, like the English version ounce, came to be used for other lynx-sized cats, and eventually for the snow leopard.[7][8]

The word panther derives from classical Latinpanthēra, itself from the ancient Greekpánthēr (πάνθηρ).[9] The Greekpan- (πάν), meaning "all", and thēr (θήρ), meaning "prey" bears the meaning of "predator of all animals". Use of the word for a beast originated in antiquity in the Orient, probably from India to Persia to Greece.[10]

Taxonomy and evolution

The snow leopard was first described by the German naturalist Johann Christian Daniel von Schreber on the basis of an illustration in his 1777 publication Die Säugethiere in Abbildungen nach der Natur mit Beschreibungen. Schreber named the cat Felis uncia and gave its type locality as Barbary, Persia, East India, and China.[15] In 1854, the British zoologist John Edward Gray proposed the genusUncia, to which he subordinated the snow leopard under the name Uncia irbis.[16] British zoologist Reginald Innes Pocock corroborated this classification, but attributed the scientific name Uncia uncia. He also described morphological differences between snow leopards and the then-accepted Pantheraspecies.[17]

Subspecies

Following Schreber's description of the species, several snow leopard subspecies were proposed:[2]

  • U. u. uncia in Mongolia and Russia;
  • U. u. uncioides in western China and the Himalayas;
  • U. u. baikalensis-romanii was proposed for a population living in the southern Transbaikal region;[18]

Until spring 2017, there was no evidence available for recognition of subspecies.[6] Results of a phylogeographic study published in September 2017 indicate that three subspecies should be recognised: P. u. uncia in the Pamir Mountains range countries, P. u. uncioides in the Himalayas and Qinghai, and P. u. irbis in Mongolia.[19]

Phylogeny

The snow leopard is part of the Panthera lineage, one of the eight lineages of Felidae. This lineage comprises the species of Panthera and Neofelis. The Neofelis lineage diverged first from the remainder of the Felinae. Subsequent branching between the snow leopard and clouded leopard began two to three million years ago, but the details of this are disputed.[20] Results of a phylogenetic study published in 2006, based on nDNA and mtDNA analysis, indicate that snow leopard and tiger are sister taxa, whereas the leopard is sister taxon to two clades within Panthera – one consisting of the tiger and the snow leopard, and the other of the lion and the jaguar.[11] Results of a similar study published in 2009 corroborated this assessment.[12] Results obtained during two subsequent phylogenetic studies indicate a swapping in the cladogram between the leopard and the jaguar.[13][14] A 2016 study indicates that, at some point in their evolution, snow leopards interbred with lions, as their mitochondrial genomes are more similar to each other than their nuclear genomes. These results indicate that a female hybrid offspring of male ancestors of modern snow leopards and female ancestors of modern lions interbred with the male ancestors of modern snow leopards.[21]

Characteristics

The snow leopard's fur is whitish to gray with black spots on head and neck, but larger rosettes on the back, flanks and bushy tail. The belly is whitish. The fur is thick with hairs between 5 and 12 cm (2.0 and 4.7 in) long. Its body is stocky, short-legged and slightly smaller than the other cats of the genus Panthera, reaching a shoulder height of 56 cm (22 in), and ranging in head to body size from 75 to 150 cm (30 to 59 in). Its tail is 80 to 105 cm (31 to 41 in) long. Its eyes are pale green or grey in color. Its muzzzle is short and its forehead domed. Its nasal cavities are large.[22][23] It weighs between 22 and 55 kg (49 and 121 lb), with an occasional large male reaching 75 kg (165 lb) and small female of under 25 kg (55 lb).[23][24]

The snow leopard shows several adaptations for living in a cold, mountainous environment. Its body is stocky, its fur is thick, and its ears are small and rounded, features that help to minimize heat loss. Its broad paws well distribute the body weight for walking on snow, and have fur on their undersides to increase their grip on steep and unstable surfaces; it also helps to minimize heat loss. Its long and flexible tail helps to maintain balance in the rocky terrain. The tail is also very thick due to fat storage, and is very thickly covered with fur, which allows the cat to use it like a blanket to protect its face when asleep.[25]

The snow leopard cannot roar, despite possessing partial ossification of the hyoid bone. This partial ossification was previously thought to be essential for allowing the big cats to roar, but new studies show that the ability to roar is due to other morphological features, especially of the larynx, which are absent in the snow leopard.[26][27] Snow leopard vocalizations include hisses, chuffing, mews, growls, and wailing.

Distribution and habitat

The snow leopard is distributed from the west of Lake Baikal through southern Siberia, in the Kunlun Mountains, in the Russian Altai mountains, Sayan and Tannu-Ola Mountains, in the Tian Shan, across Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan to the Hindu Kush in eastern Afghanistan, Karakoram in northern Pakistan, in the Pamir Mountains, and in the high altitudes of the Himalayas in India, Nepal, and Bhutan, and the Tibetan Plateau. In Mongolia, it is found in the Mongolian and Gobi Altai Mountains and the Khangai Mountains. In Tibet, it is found up to the Altyn-Tagh in the north.[4][28]

Potential snow leopard habitat in the Indian Himalayas is estimated at less than 90,000 km2 (35,000 sq mi) in the states of Jammu and Kashmir, Uttarakhand, Himachal Pradesh, Sikkim, and Arunachal Pradesh, of which about 34,000 km2 (13,000 sq mi) is considered good habitat, and 14.4% is protected. In the beginning of the 1990s, the Indian snow leopard population was estimated at roughly 200–600 individuals living across about 25 protected areas.[4]

In summer, snow leopards usually live above the tree line on mountainous meadows and in rocky regions at altitudes from 2,700 to 6,000 m (8,900 to 19,700 ft). In winter, they come down into the forests to altitudes around 1,200 to 2,000 m (3,900 to 6,600 ft). Snow leopards prefer rocky, broken terrain, and can travel without difficulty in snow up to 85 cm (33 in) deep, although they prefer to use existing trails made by other animals.[23]

Global warming has caused the tree line to be increased in altitude, resulting in the decrease of wild prey that depend on the plants for food.[29]

Population

Before 2003, the total wild snow leopard population was estimated at 4,080 to 6,500 individuals.[4] In 2016, the global population was estimated at 4,678 to 8,745 individuals, suggesting that the total number of snow leopards was larger than previously thought.[3]

Snow leopards were also recorded by camera traps at 16 locations in northeastern Afghanistan's isolated Wakhan Corridor.[34]

Ecology and behavior

The snow leopard is solitary, except for females with cubs. They rear them in dens in the mountains for extended periods.[citation needed]

An individual snow leopard lives within a well-defined home range, but does not defend its territory aggressively when encroached upon by other snow leopards. Home ranges vary greatly in size. In Nepal, where prey is abundant, a home range may be as small as 12 km2 (5 sq mi) to 40 km2 (15 sq mi) and up to five to 10 animals are found here per 100 km2 (39 sq mi); in habitats with sparse prey, though, an area of 1,000 km2 (386 sq mi) supports only five of these cats.[26] However, a new study lasting from 2008 to 2014 indicates their ranges are much greater than believed; a male snow leopard requires a territory of around 80 square miles, while females require up to 48 square miles of territory. Taking this data into account, it is estimated that 40 percent of the 170 protected areas in place are smaller than the space required to support a single male snow leopard.[35]

Like other cats, snow leopards use scent marks to indicate their territories and common travel routes. These are most commonly produced by scraping the ground with the hind feet before depositing urine or scat, but they also spray urine onto sheltered patches of rock.[23]

Snow leopards are crepuscular, being most active at dawn and dusk.[36] They are known for being extremely secretive and well camouflaged.

Hunting and diet

The snow leopard is a carnivore and actively hunts its prey. It is an opportunistic hunter and also eats carrion. It can kill animals two to four times its own weight, such as Himalayan blue sheep, Himalayan tahr, markhor, argali, horse, and camel.[37] It prefers prey ranging in weight from 36 to 76 kg (79 to 168 lb), but also hunts smaller mammals such as marmot, pika and vole species.[38]

Snow leopards prefer to ambush prey from above, using broken terrain to conceal their approach. They will actively pursue prey down steep mountainsides, using the momentum of their initial leap to chase animals for up to 300 m (980 ft). They kill with a bite to the neck, and may drag the prey to a safe location before feeding. They consume all edible parts of the carcass, and can survive on a single bharal for two weeks before hunting again. Annual prey needs appears to be 20–30 adult blue sheep.[1][23]

The snow leopard is capable of killing most animals in its range, with the probable exception of the adult male yak. It also eats a significant amount of vegetation, including grass and twigs.[23] Snow leopards have been recorded to hunt in pairs successfully, especially mating pairs.[39]

The diet of the snow leopard varies across its range and with the time of year, and depends on prey availability. In the Himalayas, it preys mostly on Himalayan blue sheep and Siberian ibex. In the Karakoram, Tian Shan, Altai and Mongolia's Tost Mountains, its main prey consists of Siberian ibex, Thorold's deer, Siberian roe deer and argali.[38][40] Other species hunted when available include red panda, wild boar, langur monkey, snow cock and Chukar partridge.[36]

Where snow leopards prey on domestic livestock, they are subject to conflict with humans.[1] However, even in Mongolia, where wild prey has been reduced, and interactions with humans are common, domestic livestock, mainly domestic sheep, comprises less than 20% of snow leopard diet.[40] Herders kill snow leopards to prevent them from taking their livestock.[25] The loss of prey animals due to overgrazing by domestic livestock, poaching, and defense of livestock are the major drivers for the decreasing population of the snow leopard. The snow leopard has not been reported to attack humans, and appears to be the least aggressive to humans of all big cats. As a result, they are easily driven away from livestock; they readily abandon their kills when threatened, and may not even defend themselves when attacked.[23]

Reproduction and life cycle

Snow leopards are unusual among large cats in that they have a well-defined birth peak. They usually mate in late winter, marked by a noticeable increase in marking and calling. Snow leopards have a gestation period of 90–100 days, so the cubs are born between April and June. Oestrus typically lasts from five to eight days, and males tend not to seek out another partner after mating, probably because the short mating season does not allow sufficient time. Paired snow leopards mate in the usual felid posture, from 12 to 36 times a day.[23]

The mother gives birth in a rocky den or crevice lined with fur shed from her underside. Litter sizes vary from one to five cubs, but the average is 2.2. The cubs are blind and helpless at birth, although already with a thick coat of fur, and weigh from 320 to 567 g (11.3 to 20.0 oz). Their eyes open at around seven days, and the cubs can walk at five weeks and are fully weaned by 10 weeks.[23] Also when they are born, they have full black spots which turn into rosettes as they grow to adolescence.[citation needed]

The cubs leave the den when they are around two to four months of age, but remain with their mother until they become independent after around 18–22 months. Once independent, they may disperse over considerable distances, even crossing wide expanses of flat terrain to seek out new hunting grounds. This likely helps reduce the inbreeding that would otherwise be common in their relatively isolated environments. Snow leopards become sexually mature at two to three years, and normally live for 15–18 years, although in captivity they can live for up to 25 years.[23][41]

Threats

The major threat to snow leopard populations is poaching and illegal trade of skins and body parts. In China, 103 to 236 animals are poached every year, in Mongolia between 34 and 53, in Pakistan between 23 and 53, in India from 21 to 45, and in Tajikistan 20 to 25. Poaching is linked to prey declines and livestock depredation.[42]

Conservation

Numerous agencies are working to conserve the snow leopard and its threatened mountain ecosystems. These include the Snow Leopard Trust, the Snow Leopard Conservancy, the Snow Leopard Network, the Cat Specialist Group, and the Panthera Corporation.

These groups and various national governments from the snow leopard’s range, nonprofits, and donors from around the world worked together at the 10th International Snow Leopard Conference in Beijing. Their focus on research, community programs in snow leopard regions, and education programs are aimed at understanding the cat's needs, as well as the needs of the villagers and herder communities juxtaposed with the snow leopards' habitats.[43][44]

Global Snow Leopard Forum

In 2013, government leaders and officials from all 12 countries encompassing the snow leopard's range (Afghanistan, Bhutan, China, India, Kazakhstan, Kyrgyz Republic, Mongolia, Nepal, Pakistan, Russia, Tajikistan, and Uzbekistan) came together at the Global Snow Leopard Forum (GSLF) initiated by the President Almazbek Atambayev of the Kyrgyz Republic, and the State Agency on Environmental Protection and Forestry under the government of the Kyrgyz Republic. The meeting was held in Bishkek, the capital of the Kyrgyz Republic, and all countries agreed that the snow leopard and the high mountain habitat it lives in need trans-boundary support to ensure a viable future for snow leopard populations, as well as to safeguard their fragile environment. The event brought together many partners, including NGOs like the Snow Leopard Conservancy, the Snow Leopard Trust, and the Nature and Biodiversity Conservation Union. Also supporting the initiative were the Snow Leopard Network, the World Bank's Global Tiger Initiative, the United Nations Development Programme, the World Wild Fund for Nature, the United States Agency for International Development, and Global Environment Facility.[citation needed]

Bishkek Declaration

At the GSLF meeting, the 12 range countries signed the Bishkek Declaration to "acknowledge that the snow leopard is an irreplaceable symbol of our nations' natural and cultural heritage and an indicator of the health and sustainability of mountain ecosystems; and we recognize that mountain ecosystems inhabited by snow leopards provide essential ecosystem services, including storing and releasing water from the origins of river systems benefitting one-third of the world’s human population; sustaining the pastoral and agricultural livelihoods of local communities which depend on biodiversity for food, fuel, fodder, and medicine; and offering inspiration, recreation, and economic opportunities." [45]

Global Snow Leopard and Eco-system Protection Program

Out of these efforts was formed a cooperative support effort, the Global Snow Leopard and Eco-system Protection Program (GSLEP). The GSLEP is a joint initiative of range country governments, international agencies, civil society, and the private sector. Its goal is to secure the long-term survival of the snow leopard in its natural ecosystem.

The goal of the GSLEP is for the 12 snow leopard range countries, with support from conservation agencies, NGOs and others to work together to identify and secure at least 20 healthy populations of snow leopards across the cat’s range by 2020, or "20 by 2020". Many of these populations will cross international boundaries.

The three criteria that will secure healthy populations of snow leopards are populations that represent at least 100 breeding age snow leopards, contain adequate and secure prey populations and have connectivity to other snow leopard populations.

This is an interim goal for the years through to 2020. During the coming years, agreement will be reached on the steps needed to achieve the ultimate goal of ensuring that healthy snow leopard populations remain the icon of the mountains of Asia for generations to come. [46]

2015 designated International Year of the Snow Leopard

To help spread the word amongst the people, government authorities, and conservation groups in each range country, 2015 was designated the International Year of the Snow Leopard as part of the GSLEPP's work. All range-country governments, nongovernmental and inter-governmental organizations, local communities, and various private sector businesses pledged to take the year as an opportunity to further work towards conservation of snow leopards and their high-mountain ecosystems.[47]

In captivity

In 2008, there were approximately 600 snow leopards in zoos around the world.[36] In the Richmond Metropolitan Zoo in Virginia, in the United States of America, snow leopard cubs were born in 2016.[48]

Much progress has been made in securing the survival of the snow leopard, with them being successfully bred in captivity. Females usually give birth to two to three cubs in a litter, but can give birth to up to seven in some cases.

Relationships with humans

Attacks on humans and livestock

Snow leopard attacks on humans are rare; only two instances are known.[49] On July 12, 1940, in Maloalmaatinsk gorge near Almaty, a rabid snow leopard attacked two men during the day and inflicted serious injuries on both.[49] In the second case, not far from Almaty, an old, toothless, emaciated snow leopard unsuccessfully attacked a passerby in winter; it was captured and carried to a local village.[49] There are no other records of any snow leopard attacking a human being.[50][51]

A 2008 Natural World episode, "Snow Leopard – Beyond the Myth", interviewed a couple with a goat farm in Pakistan; the woman was bowled over by a snow leopard escaping an enclosure where it had been feeding on the livestock, but she was not attacked by the cat, despite fainting and being helpless. The film crew went to some lengths to demonstrate that the cat was primarily hunting wild prey and was often ranging far outside the area, as they hoped to prevent local farmers from shooting it. Nevertheless, they also found evidence of other sightings of the cats around nearby human settlements, and of repeated attacks on livestock (some of them unsuccessful).[52] Snow leopards attacking livestock has also been a subject of conservation journal papers.[37]

In culture

Snow leopards have symbolic meaning for Turkic peoples of Central Asia, where the animal is known as irbis or bars, so it is widely used in heraldry and as an emblem.

The snow leopard in heraldry is sometimes known in English as the ounce. The cat has long been used as a political symbol, the Aq Bars ('White Leopard'), by Tatars, Kazakhs, and Bulgars, among others. A snow leopard is found on the official seal of the city of Almaty, Kazakhstan, and the former 10,000 Kazakhstani tenge banknote also featured one on the reverse. A mythical winged Aq Bars is found in the national coat of arms of Tatarstan, the seal of the city of Samarqand, Uzbekistan, and (also with a crown) the old coat of arms of the Kazakh capital, Astana. In Kyrgyzstan, it has been used in highly stylized form in the modern emblem of the capital, Bishkek, and the same art has been integrated into the badge of the Kyrgyzstan Girl Scouts Association. A crowned snow leopard features in the arms of Shushensky District, Krasnoyarsk Krai, Russia.

The Snow Leopard award, given to Soviet mountaineers who scaled all five of the Soviet Union's 7,000-meter peaks, is named after the animal, but does not depict one.[citation needed]

The cat is the state animal of Himachal Pradesh, a north Indian state in the western Himalayas. The animal has also been declared the "National Predator" of Pakistan.[53]

In the media

Documentary

Documentary footage of the snow leopard is scarce. While such coverage would not be remarkable with regard to common species, wildlife video of the snow leopard is difficult to obtain due to the animal's rarity and the human inaccessibility of much of its natural habitat.[52]

The BBC One TV series Planet Earth had a segment on snow leopards. The series took some of the first video of snow leopards in the wild, and also featured a snow leopard hunting a markhor.[54] The episode Mountains of Planet Earth II, aired in November 2016, featured the rather violent mating fights of snow leopards, as well as a snow leopard's chuffing and wailing.

Nisar Malik, a Pakistani journalist, and Mark Smith, a cameraman who had worked on the Planet Earth segment, spent a further 18 months filming snow leopards in the Hindu Kush for the BBC Two series Natural World episode "Snow Leopard – Beyond the Myth".[52][55] The cat has been featured in segments of other episodes of the same series.

The PBS/WNET series Nature focused on the species in its episode "Silent Roar: Searching for the Snow Leopard".

A snow leopard named Dawa along with her cubs is one of the focal points of the 2017 Disneynature film Born in China.

Non-fiction

In Peter Matthiessen's 1978 travelogue The Snow Leopard, he recounts his two-month search with naturalist George Schaller for snow leopards in Nepal.

Fictional

In Philip Pullman's 1995–2000 fantasy trilogy His Dark Materials, Lord Asriel's dæmon is a snow leopard named Stelmaria.

Tai Lung, the main antagonist of the 2008 film Kung Fu Panda, is an anthropomorphized snow leopard.

In the 2013 film The Secret Life of Walter Mitty, photojournalist Sean O'Connell (played by Sean Penn) is shown photographing snow leopards in Afghanistan.
