The red brocket deer (Mazama temama) is one of the least studied species of deer in Latin America. In México, little information is available on this species in mountainous regions, particularly in mountain cloud forests (MCF) in the state of Hidalgo. Since red brocket deer and MCF are threatened, mainly by anthropogenic activities, it is essential to carry out monitoring to corroborate the presence of this species in the MCF of Hidalgo. Here we report new records of this species in MCF of northeastern Hidalgo, in a forest management unit. The study was carried out in the 1302 Zacualtipán-Molango Forest Management Unit (UMAFOR) as part of the Strengthening of Social Organizations in the Forestry Sector project of the 2016 National Forestry Program. Monthly walks were carried out in different locations (sites) within the area between January 2016 and February 2019. The presence of red brocket deer was inferred from evidence of scats, tracks, direct sightings, and photographic records. For the latter, trap cameras were placed at sites identified as likely wildlife passes. We obtained 20 records (1 track, 2 scats, 1 sighting, 16 photographs) of red brocket deer. The sighting consisted of an adult individual being chased by seemingly feral dogs. These records provide up-to-date information on the distribution of red brocket deer in MCF in northeastern Hidalgo. To note, records were obtained in an area subjected to forest use under sustained anthropogenic impact. However, owners dedicate their premises to conservation, specifically those including MCF. Since red brocket deer thrives in conserved forests, the records reported here suggest positive effects of forest management on this UMAFOR. Biological monitoring in the area should be continued and extended, also covering areas subject to forest exploitation, as feral dogs may undermine red brocket deer populations. Finally, we recommend the development of research projects in the area, to contribute to management plans aiming to preserve red brocket deer populations.
