It's actually pretty obvious.

Even the most sensitive tourism might be bad for wildlife
A new re****t, written by Sarah E. Reed & Adina M. Merenlender of the
Department of Environmental Science, Policy & Management, University
of California, Berkeley, CA, USA, suggests that even the most
sensitive forms of tourism might be bad for wildlife.
August 2008. Protected areas around the world were created with the
goals of preserving biodiversity and providing nature-based recreation
op****tunities for millions of people. This dual mandate guides the
management of the majority of the world's protected areas, but there
is growing evidence that quiet, non-consumptive recreation may not be
compatible with biodiversity protection. We combined non-invasive
survey techniques and DNA verification of species identifications to
survey for mammalian carnivores in 28 parks and preserves in northern
California. Paired comparisons of neighbouring protected areas with
and without recreation revealed that the presence of dispersed,
non-motorized recreation led to a five-fold decline in the density of
native carnivores and a substantial ****ft in community composition
from native to non-native species. Demand for recreation and
nature-based tourism is forecasted to grow dramatically around the
world, and our
findings suggest a pressing need for new approaches to the
designation and management of protected areas.
-----------
Wilderness areas.
This re****t makes a strong case for wilderness areas. Like marine
reserves, if a core area of a wilderness is protected as just that,
wilderness, while wildlife viewing, trekking etc are allowed on the
margins, then that would provide the best of both worlds.

I am working on creating wildlife habitat that is off-limits to
humans ("pure habitat"). Want to help? (I spent the previous 8
years fighting auto dependence and road construction.)
