Bharatpur sanctuary beneath risk from alien species: Report | India News

NEW DELHI: An worldwide examine that used a brand new methodology to classify threat of organic invasions in world heritage websites has discovered that Rajasthan’s Keoladeo National Park, previously often called the Bharatpur Bird Sanctuary, is going through a “high threat” from invasive alien species, with as many as 14 such species thriving on the planet heritage web site.
Keoladeo was recognized as going through ‘low risk’ within the invasive alien species risk stage indicated within the 2017 IUCN World Heritage Outlook — the primary international evaluation of pure world heritage. But in a brand new examine printed within the journal Biodiversity and Conservation, researchers have categorised the location as going through ‘excessive risk’ from organic invasions.
The examine famous that efforts to handle invasive plant species have been going down in Keoladeo however warned that threats are growing and the location is more likely to be incapable of going through future challenges.
The researchers consulted with consultants from Dehradun-based Wildlife Institute of India (WII) and combed by way of literature whereas utilizing a newly developed methodology of threat evaluation to determine 14 species that may be thought of to be invasive within the park.

The new strategy recognized vegetation as the commonest invasive species (9) adopted by two forms of fish — widespread carp and African catfish. Two mammals — bovine (Bos taurus) and rhesus monkey (Macaca mulatta) — and a moth species (Parapoynx diminutalis) have been additionally recognized as invasive.
“Most of these species are known to cause high threats and impacts elsewhere in India and in many regions of the world,” lead creator Ross Shackleton, school member on the University of Lausanne (Switzerland), instructed TOI. “While species like the Clarias gariepinus (African catfish) and Prosopis juliflora (a tree) are being managed, not much progress has been made. This is also the case in many protected areas which face threat from invasions despite management,” he stated.
The new methodology developed by Shackleton and his staff lays a step-by-step process to gather data and to report on pathways by way of which alien species are spreading, assessing their influence and administration in addition to predicting future risk and administration wants, discovering the standing of data and gaps and assigning an total ‘risk rating’ to the protected space.
Formal surveys on the location may reveal extra invasive species, the researchers stated. Professor Okay Sivakumar, head of the division of endangered species administration at WII, who lent his insights to the examine stated there may simply be greater than 50 invasive alien species on the location. “We have never done a detailed study to identify invasive species or the routes through which they are spreading,” he stated.
Sivakumar stated not sufficient consideration has been paid to invasive alien species regardless that the nation wants a coverage or an invasive alien species Act to take care of them on battle footing and scale back the risk to biodiversity. “Most tiger habitats in the country have been invaded by lantana (a shrub) while common water hyacinth (Eichhornia crassipes) is choking our wetlands. Another major threat is P juliflora trees which encroach on the wetland,” he stated.
While the most recent framework used within the new examine would assist researchers, for the administration to implement it on the bottom we’d like clear coverage pointers, stated Sivakumar.
Mohit Gupta, deputy conservator of forests (DCF), wildlife, Bharatpur, admitted that invasive alien species are among the many largest threats to the park ecosystem however added that their administration was a long-term course of. “Invasive alien species is a vital side of park administration proper now. We are eradicating invasive species yearly however that is extra of a symptomatic therapy and a short-term measure. So as a long-term strategy, now we have renewed our deal with reviving the fundamental ecology and pure processes of the park.”
