Forest ecosystems, where natural resource users are potentially in conflict with conservationists, are extremely threatened by various external factors. Resulting loss of forest cover and land-use change can have a great impact on the provision of ecosystem services (such as watershed regulation, biodiversity maintenance). However, little is known on a global scale about the character and distribution of threats to forest biosphere reserves. In view of this knowledge gap, our analysis explores the occurrence of threats and their potential causes. A global telephone survey of UNESCO biosphere reserve managers was conducted. Upon pinpointing climate change (in high-income countries) and illegal activities (in non-high-income countries) as major threats, we identified the group of forest-specific illegal activities (wildfire and its precursors) as an occurrence chiefly predominant in non-high-income countries. Our results show that forest biosphere reserves in non-high-income countries are particularly under extreme threat, as they have to address both climate change and illegal activities, while the latter are less problematic in high-income countries.
thnq......bt do uh have any other info. about it ??

Threats to bio reserves are
----------------------------------------------
1)FOREST FIRES
---------------------------
it causes a lot of damage to the bio reserves as it can spreads to thousands of sq km and destroy all the trees it is mainly due to some explosive things carried by people or some people throw cigarettes which will cause fire
-----------------------------------------------------------------
2)THREAT BY HUNTERS ETC
-------------------------------
some people go for hunting in bio reserves even tho its not allowed to do so but they hunt or cut off some valuable trees for money even if there is high security
------------------------------------------------------------------------
3)CORRUPTION
-------------------------
some of the leader do corruption and gets involved in illegal activities in forest in collaboration with the forest guards like cutting sandalwood trees etc in order to make money
---------------------------------------------------------------------------------
4)CLIMATE CHANGE
-------------------------
change in climate also harms the bio reserves as some of them grow in a particular climate and in some type of climate they may die
-------------------------------------------------------------------------------------
5)GLOBAL WARMING , POLLUTION , WATER SCARCITY
-----------------------------------
it is also one of the major threat too the bio reserves , due to high temperature trees may die and pollution will effect the animals present in it
due to water scarcity plants and animals wont get enough water and they may die
