The volcano rabbit has been severely pressured by human intrusion into its habitat.
Habitat. Considering the habitat of the Volcano Rabbit is a mere 45 minutes from the city of Mexico D.F., it should come as no surprise that highway construction and urban development are encroaching on the ecosystem. Volcano rabbit species is found only on the slopes of two volcanic mountain ranges in central Mexico.
The rather surprising Volcano Rabbit has a natural habitat range that remains limited to only one specific portion of the world. The volcano rabbit—a shrinking distribution and a threatened habitat - Volume 21 Issue 2 - J. Hoth, A. Velazquez, F. J. Romero, L. Leon, M. Aranda, D. J. Volcano rabbits are an endangered species endemic to Mexico. These mountains harbour an unusual habitat known as zacaton. Bell  Specifically, the rabbit is native to four volcanoes just south and East of Mexico City, the largest of these volcanic regions is within the Izta-Popo National Park, other areas include the Chichinautzin and Pelado volcanos.
For example, the volcano rabbit of Mexico is only found on the slopes of four volcanoes near Mexico City. Habitat Volcano Rabbits can be found on the volcanic slopes in central Mexico.
The dark coloration of their fur blends well with the rocky, volcanic soils of their habitat.
The volcano rabbit, or zacatuche, inhabits dense undergrowth of bunchgrass in pine forests in the high mountains surrounding Mexico City. Specifically, the highways’ physical barriers are causing the further fragmentation of the already patchy clusters of rabbits, which increases the likelihood of extinction. This is a dry, high-altitude pine woodland where clumps of grass grow under the trees. For survival, volcano rabbits depend on zacaton bunchgrass—a tall, dense grass that grows in thick clumps on the alpine slopes where the rabbits live. The four volcano slopes where these unique rabbits reside are the Tlaloc, El Pelado, Iztaccihuatl and Popocatepetl volcano slopes. Volcano Rabbit Distribution, Habitat, and Ecology. On average, they weigh about one pound and are about 30 centimeters (12 inches) long. That’s due to the fact that its only known habitat consists of certain rugged mountains of Mexico, in North America.
The cottontail rabbit, Sylvilagus, is expanding into the volcano rabbit’s niche, but there is “no evidence that [volcano rabbits'] habitat selection is a response to competitive exclusion." They have a restricted range and they are usually found in pine forests at elevations between 2,800 and 4,250 m (9,186 - 13,944 ft). The Volcano rabbits tend to be found in the dense pin forests and undergrowth that covers the volcano slopes and usually at around 3000 meters in elevation.
A population of only about 6,000 remains in fragments of habitat.
