Madagascar’s Mysterious Fossa | National Geographic


Madagascar politically is a part of
Africa but it is an island unto itself
it’s been called the eighth continent
because it is so different it’s been
this isolated world unto itself for so
long and that’s why everything here is
so unique not a lot of people know about
the fusa the fusa is the largest
carnivore on madagascar a booth is a
pretty unique animal if I had to imagine
what the common ancestor between the
mongooses the cats and the hyenas look
like I imagine it would look a lot like
a Fuson boosah while they may be
relatively ubiquitous they may be found
in all forest types in madagascar
they’re locally rare I estimate that
there’s definitely fewer than 3,000 fusa
left in the wild
while food may be found in undisturbed
forests throughout the island they’re
often the first things to go as well
they’re pretty sensitive to human
impacts as a biologist who studying the
species I spend
more of my time working on the
conservation of the species than just
the biological study of it will put
large trap bonds that can extend 20
kilometers every 500 meters maybe we’ll
have a trap
seeing healthy females is a really good
indication that even though the
population size may be small it’s doing
well and has a chance to sustain itself
into the future the invasive species is
an organism plant and animal that is
somewhere that it doesn’t belong and it
shouldn’t be naturally occurring it can
really very quickly upset the balance of
nature that has taken so longer
naturally evolved they can be animals
like domestic dogs supplier dogs a
problem dogs and Madagascar aren’t
usually kept as pets in the traditional
sense
there are round villages they bark at
intruders it’s people like keeping them
around but they’re not regularly
provision in the last few years domestic
dogs have gone from sort of being on the
outskirts of villages to forming roving
packs throughout the forests here I’ve
watched the fusa populations go from a
consistent stable level to a reduced
level and then having been completely
locally extirpated and oftentimes around
villages near national parks they start
finding their foods from within the
forest now that provides a direct
competition for the fusa and other
wildlife like I study when I see a dog I
see a kilo of biodiversity disappearing
every few days as dog populations
increased i watch snake populations
decrease i watch brown bird populations
decrease
if you say don’t have food they don’t
survive the animal I’m studying guys we
intervened we had to remove the dogs
from the forest we’ve tried every
possible solution when we trap dogs
we’ve relocated them 50 60 70 kilometres
away we’re also trying to prevent their
resurgence by doing spay and neuter
clinics all through the park the
platypus Laden cut a little
we survived based on what we can take
from nature and how we can coexist with
animals plants people if we lose any
part of it we’re going to lose all of
them we can’t let that happen
