Jayamangali (formerly Maidenahalli) Blackbuck Conservation Reserve is Tumkur district's only notified protected area.

It neighbours Maidenahalli, a small village in Madhugiri Taluk, at the north-eastern tip of Tumkur district of Karnataka state, India.

Post- independence, however, they have shrunk to isolated patches thanks to immense pressure for cultivation, human habitation and other reasons that also include industrialisation.

In 1987, the forest department of Tumakuru Division began protecting the area when the blackbuck’s presence was brought to their notice.

The first ever Status Survey report on the area was published by Tumakuru-based Wildlife Aware Nature Club (WANC) in 1997.

This helped the wildlife wing of Karnataka Forest Department to source data on this area and recommend it be declared a 'Conservation Reserve'.

The geographical co-ordinates of the forest watch tower inside this area are 13 44’ 20" N and 7 19’ 41" E. It is located 4 km away from the Jayamangali Blackbuck Conservation Reserve.

In total, 19 species of mammals belonging to 11 families have been recorded in the area, including the near threatened blackbuck.
