mistletoes; among these are Deschampsia caespitosa (a very rare tussock grass), Peraxilla tetrapetala (a vulnerable mistletoe) and Libertia peregrinans (a possibly locally extinct sand iris). The 2009 culling of the population removed 230 horses from the herd, the largest culling since the beginning of the program, with homes found for 85% of the horses removed. Conservation of these horses is an important matter to the public, and between 1990 and 2003 the New Zealand Minister for Conservation received more public comments on the Kaimanawa horse than on any other subject. In this period, more than 1,400 requests for information and letters were received, with public interest peaking in 1996 and 1997. This was due to a program of population reduction by shooting scheduled to begin implementation in 1996; due to public opposition the shooting was cancelled and a large scale muster and adoption program began in 1997. In 1997, around 1,069 horses were removed from the range and adopted, reducing the main herd to around 500, and reducing their range to around 25,000 ha from around 70,000. Since 1993, a total of around 2,800 horses have been removed from the range. Only one injury resulting in the death of a horse is known to have occurred. The United Nations' Food and Agricultural Organization lists the Kaimanawa horses as a herd of special genetic value that can be compared with other groups of feral horses such as New Forest ponies, Assateague ponies, wild Mustangs, and with free-living zebras. Kaimanawas are of special value because of their low rate of interaction with humans. This lack of interaction may result in a herd with more wild and fewer domestic characteristics, which is of special interest to researchers. Between 1994 and 1997, students from Massey University studied a population of around 400 Kaimanawa horses to learn their habits and herd dynamics. A 2000 study found that although sometimes there are more than two stallions in Kaimanawa horse herds, only the two stallions highest in the herd hierarchy mate with the herd females. This differs from other feral horse herds, some of which have only one stallion that mates with mares, while others have several stallions that sire foals.
