Abstract
The seasonal forest formations of the Atlantic Forest are a threatened and poorly known habitat. We present here a list of the non-volant mammals occurring in a 515‑ha forest fragment known as Santa Maria and located in the Brazilian state of São Paulo. Our surveys are based on live trap captures, camera traps, and active searches for footprints, as well as secondary data. We list 29 species of non-volant mammals in the fragment, recorded between 1996 and 2021. One species found in the fragment, Leontopithecus chrysopygus, is globally endangered. Two species are classified as "vulnerable" in the global red list: Myrmecophaga tridactyla, and Tapirus terresris. One species, Panthera onca, is classified as "critically endangered" in São Paulo state. The red howler, Alouatta guariba, was not recorded after 1999 and has probably been extirpated in the fragment. We show that the number of non-volant mammal species in Santa Maria fragment is high, in relation to its size. The fragment is also in a strategic position, between the Morro do Diabo state park and the Black Lion Tamarin Ecological station, the two largest protected areas in the region. Considering its high mammal richness and its possible role as stepping stone for the local fauna, we recommend that the fragment become a protected area.

The Atlantic Forest, a South American forest ranging from northeastern Brazil to northern Argentina and eastern Paraguay, is known for its elevated biodiversity and endemism (Mittermeier et al, 2011)

Summary
The Atlantic Forest, a South American forest ranging from northeastern Brazil to northern Argentina and eastern Paraguay, is known for its elevated biodiversity and endemism (Mittermeier et al, 2011). It is a highly threatened ecosystem, as only 28% of its original forest cover remains (Rezende et al, 2018; Ribeiro et al, 2009). 40,000 ha of this type of forest are inside protected areas such as the Morro do Diabo State Park (MDSP) with approximately 33,800 ha and the Black Lion Tamarin Ecological Station with approximately 6,700 ha, distributed in four sep-
