Abstract Landscape connectivity is essential in biodi-
versity conservation because of its ability to reduce the
effect of habitat fragmentation; furthermore is a key prop-
erty in adapting to climate change. Potential distribution
models and landscape connectivity studies have increased
with regard to their utility to prioritizing areas for con-
servation. The objective of this study was to model the
potential distribution of Mountain cloud forests in the
Transversal Volcanic System, Michoacán and to analyze
the role of these areas in maintaining landscape con-
nectivity. Potential distribution was modeled for the
Mountain cloud forests based on the maximum entropy
approach using 95 occurrence points and 17 ecological
variables at 30 m spatial resolution. Potential connectivity
was then evaluated by using a probability of connectivity
index based on graph theory. The percentage of variation
(dPCk) was used to identify the individual contribution of
each potential area of Mountain cloud forests in overall
connectivity. The different ways in which the potential
areas of Mountain cloud forests can contribute to con-
nectivity were evaluated by using the three fractions derived
from dPCk (dPCintrak, dPCfluxk, and dPCconnectork). We
determined that 37,567 ha of the TVSMich are optimal for
the presence of Mountain cloud forests. The contribution of
said area in the maintenance of connectivity was low. The
conservation of Mountain cloud forests is indispensable,
however, in providing or receiving dispersal flows through
TVSMich because of its role as a connector element
between another habitat types. The knowledge of the
potential capacity of Mountain cloud forests to promote
structural and functional landscape connectivity is key in
the prioritization of conservation areas.

Introduction
In a global context, mountain forests play a fundamental
role in biodiversity conservation, hydric regulation of large
watersheds and carbon storage. For this reason, there is a
greater need to conserve remnant areas as an adaptive
strategy for mitigating climate change (Spracklen and
Righelato 2014). These areas also provide cultural value in
terms of esthetic, spiritual and recreation value of great
importance in a world increasingly transformed by human
activities (Price et al. 2011).
In Mexico, the Mountain cloud forests (MCF) are known
as “mesophylous mountain forests”, and at a global level
