Chapter 9 – Conservation Outside Protected Areas
- Most PAs too small to protect long-term pops
- Many species attracted to resources outside protected areas
- Many species migrate between PAs seasonally to avoid climate extremes or access mates
and other resources
- The smaller a PA, more dependent it is on neighboring unprotected lands for long-term
biodiversity
- Very important to protect biodiversity inside and outside PAs
- Reconciliation ecology – ways to promote biodiversity in human-dominated landscape
o Creating habitat in urban settings
- Conservation outside PAs should strive to blur distinctions between protected and
unprotected ecosystems by maintaining unprotected ones in state of reasonable ecological
health
The Value of Unprotected Habitat
- Significant proportions are not used intensively by humans and still harbor some original
biota
- Numerous rare species and ecosystems exist on unprotected public or private lands
- Types of land not contained within traditional PAs but still important for biodiversity
o Military land
▪ Much of land is unused, which makes it good land for species
▪ When it is not needed anymore, great candidates for PAs
▪ Some contain toxic waste dumps and high levels of chem pollutants
▪ Severe disturbances in some areas (explosions, heavy vehicles, etc.)
o Unprotected forests
▪ May still have a considerable % of original biota and maintain most
ecosystem services
o Unprotected grasslands
▪ Mowed spaces provide open grassland habitat
▪ Power line corridors have high densities of birds, insects, etc.
▪ Remnant prairies in the US good for many grassland species
o Unprotected waters
▪ Most marine plant diversity occurs outside of PAs
▪ Animals migrate across huge expanses which are not protected
▪ Higher abundance in MPAs than outside of them
o Land that is undesirable to humans
▪ Demilitarized areas
▪ Desert and tundra ecosystems
o Private land
▪ Estates usually used at low intensity, often deliberate attempt to maintain
large wildlife populations
▪ Small yards and home gardens
• Insects
Conservation in Urban and Other Human-Dominated Areas
- Native species can persist in urban areas

Document Summary
Most pas too small to protect long-term pops. Many species attracted to resources outside protected areas. Many species migrate between pas seasonally to avoid climate extremes or access mates and other resources. The smaller a pa, more dependent it is on neighboring unprotected lands for long-term biodiversity. Very important to protect biodiversity inside and outside pas. Reconciliation ecology ways to promote biodiversity in human-dominated landscape: creating habitat in urban settings. Conservation outside pas should strive to blur distinctions between protected and unprotected ecosystems by maintaining unprotected ones in state of reasonable ecological health. Significant proportions are not used intensively by humans and still harbor some original biota. Numerous rare species and ecosystems exist on unprotected public or private lands. Native species can persist in urban areas. Presents special challenges, but also unique opportunity to educate public. Not all species have potential to live within human-dominated landscapes. Generalist species will tend to do best.
