Leopards (Panthera pardus) face severe range loss, with some subspecies critically endangered. Despite a broad historic range, current distribution is significantly reduced, highlighting urgent conservation needs for vulnerable populations.
Area of Science:
- Conservation Biology
- Zoology
- Ecology
Background:
- Leopards (Panthera pardus) are often perceived as resilient due to their wide distribution and adaptability.
- This perception masks critical endangerment in several subspecies and regional populations.
- Range loss in leopards exceeds the average for terrestrial large carnivores.
Purpose of the Study:
- To comprehensively assess the conservation status of the leopard across its geographic range.
- To quantify historic and current distribution, identifying critically endangered subspecies.
- To evaluate the effectiveness of protected areas for leopard conservation.
Main Methods:
- Compiled over 6,000 distribution records from 2,500 locations and 1,300 sources.
- Mapped historic (post-1750) and current leopard distribution in Africa and Asia.
- Analyzed range loss and fragmentation for nine recognized subspecies.
Main Results:
- Leopards now occupy only 25-37% of their historic range.
- Three subspecies (P. p. orientalis, nimr, japonensis) have lost up to 98% of their historic range.
- Six subspecies with <100,000 km(2) extant range face threats from isolation and small, fragmented populations.
- Only 17% of extant leopard range is protected, with critically endangered subspecies having less.
Conclusions:
- Leopard conservation status is more dire than commonly perceived, with significant subspecies-specific threats.
- Urgent conservation interventions are required for highly threatened subspecies, particularly those with limited and fragmented ranges.
- Research efforts need to be redirected towards neglected, endangered subspecies to inform effective conservation strategies.

Testing a Claim about Mean: Unknown Population SD
Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used;...
