Decline
The most serious threats to the volcano rabbit are habitat degradation and target shooting. Hunters looking for game birds (such as quail) will use the rabbit for target practice. Also people took over some of the land they were living in. The people living in the mountains consider it vermin to be killed off. Neither the hunters or the natives eat the volcano rabbit.
Decreases in R. diazi population have been occurring due a number of changes in vegetation, climate, and elevation changes for the volcano rabbit. It is believed that “Climate change amplifies the decline in female abundance and the cumulative probability of decline for R. diazi” (Anderson, BJ ,1416) Climate change is seen to be detrimental to the volcano rabbit mainly because of the effect on its very specific vegetation and environment needs. Patches of vegetation that the R. diazi use for survival are becoming fragmented, isolated and smaller making the environment more open and less suitable for the small rabbit. The volcano rabbit has also had to overcome human changes in land use, pushing them further up their mountainous environment and therefore forced into a higher elevation with a less suitable environment. Human intervention within the R. diazi’s environment has proven to be the most detrimental to the rabbit’s survival. Within areas of grazing, logging, and farming showed zero R. diazi sightings of the 6,488 average provided by Alejandro Velazquez study of the rabbit’s population on El Pelado volcano, Mexico. This number compared to the 5,771 rabbits found in thick forest and grassland environments is a crucial statistic in showing that the volcano rabbit’s survival heavily relies in the environments ability to provide a proper diet as well as shelter for the small rabbit.

Famous quotes containing the word decline:
“Considered physiologically, everything ugly weakens and saddens man. It reminds him of decay, danger, impotence; it actually reduces his strength. The effect of ugliness can be measured with a dynamometer. Whenever anyone feels depressed, he senses the proximity of something “ugly.” His feeling of power, his will to power, his courage, his pride—they decline with ugliness, they rise with beauty.”
—Friedrich Nietzsche (1844–1900)
“We have our little theory on all human and divine things. Poetry, the workings of genius itself, which, in all times, with one or another meaning, has been called Inspiration, and held to be mysterious and inscrutable, is no longer without its scientific exposition. The building of the lofty rhyme is like any other masonry or bricklaying: we have theories of its rise, height, decline and fall—which latter, it would seem, is now near, among all people.”
—Thomas Carlyle (1795–1881)
“I heard a Californian student in Heidelberg say, in one of his calmest moods, that he would rather decline two drinks than one German adjective.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
