In 2003 and 2004, disaster struck Ranthambhore's tigers once again. A census conducted by the Rajasthan State Empowered committee showed that there were only 26 tigers in entire reserve and all of them were within the national park. The other areas of the reserve were totally devoid of tigers. In 2005, the Rajasthan and the Indian central government set up high powered committees to look into the state of Ranthambhore and to suggest measures to improve the situation.There have been no reports of tiger poaching from around Ranthambore from the beginning of 2005 and a large number of tiger cubs were born between the summer of 2005 and the summer of 2006. A very detailed census that was carried out by the Wildlife Institute of India using camera traps between 2006 and 2007 showed that there were 31 tigers in Ranthambhore national park.The areas surrounding the Tiger reserve have been totally deforested and as a result, the Ranthambore tiger reserve is now an "ecological island surrounded by farmlands and overgrazed pastures." It is is home to over 40 species of mammals, 320 species of birds, over 40 species of reptiles and over 300 species of plants. the Indian or the Bengal Tiger is the flagship species of Rantambhore and right now it is the only place in Rajasthan where tigers exist.
The terrain of Ranthambhore tiger reserve is mostly rugged and hilly and is intimately related to the Great boundary fault. The hills to the northwest of fault-line are the Aravalis and typically have ridges on one side and gentle slope on the other. The hills south west of Great boundary fault are the Vindhyas. The sand stone beds of these hills are flat-topped and form extensive table lands known as "Dangs". These dangs rise abruptly from flat ground and have sandstone ridges running continuously along their edges.
The Ranthambhore tiger reserve, with its sub-tropical dry climate, has three very well defined seasons - summers, winters and monsoons. October and March are the time when the weather changes from monsoons to winters and from winters to summers, respectively. Summers start during the end of March and last through the months of April, May and June. During this season the days are very hot and dry. During May and June the maximum day temperature crosses 40 degrees Centigrade and the minimum night temperature still hovers around 30 degrees Centigrade. The monsoons or the rainy season lasts from July to September. The winter season lasts from November to February.
