Nelsonia goldmani, known as Goldman's Woodrat, is a small rodent native to the arid and semi-arid regions of Mexico. It is characterized by its soft fur, bushy tail, and nocturnal habits. This species is known for its unique nest-building behavior using twigs and leaves, and plays a crucial role in seed dispersal and ecosystem health.

Nelsonia goldmani and its subspecies are native to Mexico. Specifically, the species is found in the central and southern parts of the country. Nelsonia goldmani goldmani is typically located in the highlands of central Mexico, whereas Nelsonia goldmani cliftoni is found in the southwestern regions. Nelsonia neotomodon, another related species, is also native to Mexico, predominantly found in the Mexican Plateau region.

These species are generally found in montane forests and grasslands. The climate in these regions can vary from temperate to cool, with significant rainfall, especially in the montane regions that provide a humid environment. Elevations where these species are found can range from 1,500 to 3,500 meters above sea level.

Nelsonia species occupy ecological niches that involve dense underbrush or grass cover. They are adapted to live in areas with plenty of ground cover, which provides protection from predators and a rich supply of food resources, such as seeds and small invertebrates. Their adaptations may include a tolerance for cooler, moist environments and the ability to navigate through complex vegetation structures.
