| description | Maintaining jaguar Panthera onca subpopulations throughout
Mesoamerica is vital to range-wide jaguar conservation. Corcovado National Park
in Costa Rica is critical habitat for the Osa Peninsula jaguar subpopulation.
There is a debate regarding whether the jaguars in this National Park are in a
state of crisis. To examine this, we implemented long-term camera-trap
monitoring throughout Corcovado National Park during 2015–2021. Using a
spatially explicit Jolly–Seber model we estimated jaguar populations and
distribution throughout our study area. Additionally, we reran our model using a
constrained study area to compare our findings with those of a previous study.
Trends in jaguar abundance indices and population estimates during
2015–2021 indicate that jaguar abundance has increased over time. Our
jaguar density estimates also fall within the range of jaguar densities reported
for relatively stable populations elsewhere. Using the same study area as that
of a prior study, jaguar densities also increased over the duration of our study
and were mostly comparable to previous density estimates. Our results suggest
that jaguars within Corcovado National Park may not be in a state of crisis.
Rather, our findings provide further hope for the jaguars of the Osa Peninsula.
They do not, however, diminish the importance of continued conservation efforts.
These will remain critical both inside and outside Corcovado National Park, as
threats appear to have persisted over time. |
