SHRI NAGENDRA KUMAR PRADHAN:

Will  the  Minister  of  ENVIRONMENT,  FOREST  AND  CLIMATE  CHANGE  be  pleased  to state:

- (a) whether the Government has conducted any tree census across the country to take stock of  the  country's  biodiversity  and  ensuring  protection  of  its  green  areas  and  if  so,  the details thereof;
- (b) the number of trees and details of the species identified in the survey, State-wise;
- (c) the global average of trees per person and the actual ratio in India;
- (d) the  details  of  the  decadal  growth/reduction  in  the  number  of  trees  across  the  country, State-wise; and
- (e) the extent to which tree census is encouraging community awareness of the need for tree conservation, regulating pruning and felling and increasing the green cover?

## ANSWER

## MINISTER FOR  ENVIRONMENT, FOREST AND CLIMATE CHANGE

## (DR. HARSH VARDHAN)

- (a) The Ministry does not conduct any Census of trees to take stock of biodiversity in the country. However, Forest Survey of India, Dehradun a subordinate organization under Ministry  of  Environment,  Forest  and  Climate  Change  conducts  regular  inventory  of trees  in  forests  and  outside  forests  in  the  country  under its  National  Forest  Inventory programme by  selecting  60  districts  randomly  in  different  physiographic  zones  on  a cycle of two years. On the basis of data collected from these 60 districts growing stock (stems & volume of wood) estimates are generated at national level which is published in India State of Forest Report.
- (b) The Species wise total number of trees at national level both in Forest and Tree Outside Forest (ToF) as published in India State of Forest Report - 2015 are given in Annexure I&II .
- (c) The global average of trees per  person  is  not  available.  As  per  India  State  of  Forest Report 2015, average trees per person estimated to be around 16 in India.
- (d) The decadal growth rate of number of trees at national level estimated to be 6.6% as per results published in India State of Forest Report -2005 and India State of Forest Report -2015.
- (e) The Ministry does not conduct tree census. However, Forest Survey of India, Dehradun a subordinate organization under Ministry of Environment, Forest and Climate Change prepares regular inventory of trees in forests and outside forests in the country under its National Forest Inventory programme biennially and result of forest and tree cover are published in India State of Forest Report. Such figures on increase/decrease in forest cover including inter-States differences in forest  and tree cover give more challenges and motivation to achieve future targets among people and Governments.
