Forest dept questioned for prepare to weed out 3 invasive tree species in Delhi
The proliferation of a few rapidly growing tree species of vilayati kikar, subabul and eucalyptus in the money desires a plan to contain and exterminate them, Delhi’s State Atmosphere Impact Assessment Authority has questioned the forest section in its hottest conference, following the Delhi City Art Commission lifted fears on their adverse effect on area ecology.
A pilot challenge to get rid of vilayati kikar is currently underway and the forest department is also on the lookout at techniques to deal with other invasive species like subabul and lantana, officials mentioned, requesting anonymity.
“We are checking out techniques to clear away vilayati kikar from the central ridge. If the pilot is prosperous, a similar approach could be adopted for subabul and lantana, which are in the same way invasive species in the ridge,” a forest official explained. “As these trees nonetheless type a aspect of Delhi’s inexperienced deal with, they are not able to be taken out at the very same time.”

The advice was made by the effect evaluation authority in its conference held on December 23. HT has viewed the minutes of the meeting. In a September 29 letter to the State Expert Appraisal Committee, the chairman of Delhi City Art Fee experienced highlighted the concern of three invasive species that are not native to Delhi but are creating an imbalance in its ecology.
“These species are invasive and multiplying swiftly, crowding out indigenous species and their symbiotic flora and fauna. These incorporate vilayati kikar (prosopis juliflora), subabul (leucaena leucocephala) and at last, eucalyptus,” the letter explained. This proposal was forwarded to the assessment authority on November 25.
“The SEIAA in its assembly held on December 23, 2022, has accredited the suggestion of the SEAC to ahead the reference from DUAC to the forest division of Delhi for appropriate examination and necessary action, with further intimation to the two SEAC and SEIAA,” the minutes examine.

A strategy has to be drafted by the Delhi forest section on how these species will be tackled in the lengthy-operate, a SEIAA member claimed. “They will advise us about the motion system and how they intend to clear away these exotic species,” the member mentioned, declining to be named.
Of the 3, vilayati kikar is the most damaging, as the Mexican invasive species launched by the British in the 1930s in Delhi quickly using more than massive areas of the ridge, experts mentioned.
“Vilayati kikar types practically 70% of all trees in the ridge at existing. Its roots expand over 50 metre deep, so it depletes the groundwater desk where ever it grows,” reported C.R Babu, head of the Centre for Environment Administration of Degraded Ecosystems. “The principal dilemma with it is that it does not permit indigenous species to expand all over it.”
Eucalyptus, which arrived from Australia, is not invasive in mother nature, but uses a large amount of drinking water as it is a quick-increasing tree, Babu reported. “Wherever it grows, the groundwater level will fall rapidly. It also displays allelopathic results, this means the tree releases compounds which make it tricky for other indigenous species to develop nearby,” he claimed.
Subabul, the third tree flagged in the record, also arrives from Mexico and was released by the forest office for gas and fodder, but it has developed as well swiftly, growing effectively outside of the place it was initially planted.
Though subabul is not as harmful as vilayati kikar, it still propagates speedily, in accordance to Faiyaz Khudsar, scientist in-cost at the Yamuna Biodiversity Park in north Delhi. “Like vilayati kikar, it does not allow native species to expand all over it,” he mentioned.
There has been an explosion of subabul above the previous decade or so, stated Padmavati Dwivedi, an activist. “All 3 species are not indigenous, mature rapidly and are depleting the groundwater desk,” she claimed, recommending systemic action against them.
