Emerging Conservation Needs and Priorities
When field experts conversant with the Sonoran bioregion were asked
what they felt should be the number one priority for conservation,
they responded in a variety of ways, noting policy issues, research
and education needs, action strategies, as well as earmarking species,
habitats or landscapes in critical need of conservation. We have
organized their suggestions topically, and list their comments within
each topic in no particular (weighted) order.
1. Research Needs
Among the research needs cited as conservation priorities were
the need to:
A. Realize biogeographic studies to discern regional patterns
of biodiversity.
B. Determine areas of high diversity of invertebrates, and compare
those with areas identified as high in species richness of plants
and vertebrates.
C. Identify through banding and capture-recapture the most frequently
used corridors for nectar-feeding bats, hummingbirds, monarchs
and other pollinators at risk.
D. Identify areas of high endemism across taxonomic groups.
E. Determine which habitat types have less than 8% of the area
protected.
2. Educational needs
Among the educational needs cited as conservation priorities were
the need to:
A. Increase or redirect public understanding so that laymen appreciate
the dynamics and constraints of arid ecosystems.
B. Synthesize and disseminate basic knowledge about the value
of desert ecosystems to build a larger public constituency.
C. Train indigenous residents of remote rural areas in techniques
for surveying, monitoring, restoring and conserving endemics and
locally endangered species.
D. Train and build capacity of more "rangers" and environmental
educators in all Mexican protected areas.
3. Need to shift society's consumption patterns, behaviors
and perceptions
Among the behaviors, consumption patterns and perceptions seen as
priorities for conservation education were the need to:
A. Increase family planning to control human population growth.
B. Shift away from social and economic systems that reward consumptive
behaviors and short-term gain while damaging natural systems.
C. Amend patterns of consumption to dramatically reduce the occupancy
footprint.
D. Foster conservation through promoting sustainable development
and less consumptive lifestyles or land uses.
E. Alter human values so that we are truly responsible for the
real implications of our actions.
F. Reward conservation-oriented residents and businesses by creating
disincentives for consumptive behaviors that create life risks.
G. Seek alternative economic activities for communities or families
formerly dependent on extractive activities, particularly in and
around protected areas.
H. Develop additional collaborations between field scientists,
conservationists and progressive ranchers to purchase or place
deed restrictions on land threatened with subdivision.
I. Foster reciprocal exchange of technical information on biodiversity
and threats across the intemational border, and between resident
cultures of the region.
4. Land/water management and resource protection policies
Among the land, water and resource management policies seen as conservation
priorities were the need to:
A. Halt or mitigate all barriers which are fragmenting corridors
and critical habitats required by native migratory and resident
species.
B. Establish zoning to control (urban) development with buffers
of 16 km. width around all protected areas especially where wildlands
include natural corridors such as rivers and washes.
C. Limit growth of residential and commercial occupancy to within
natural carrying capacity.
D. Preserve largest tracts of remaining habitat rich in unique
biota by limiting intrusions into them, including urban sprawl.
E. Mandate the preservation of a certain portion of natural habitats
remaining in new residential developments and industrial parks.
F. Give priority protection to areas which have artesian flows
of water into oases, cienegas or other wetlands, and to springs/seeps
of all kinds.
G. Ensure protection of coastal lagoons and estuaries as spawning
and nursery grounds.
H. Establish cross-boundary chains of reserves along riparian
and "nectar" corridors used by migratory birds and wide-ranging
mammals.
I. Establish incentives to keep current farmland from being subdivided
for urban or suburban development, and give tax breaks for pesticide
free crop production.
J. Place strict controls on the introduction and planting of exotics.
K. Protect lowland basins between mountain ranges as migratory
corridors.
5. Land, water and vegetation management practices
Among the on-ground management practices recommended were the need
to:
A. Reduce the maximum number of cows (cattle units) allowed per
grazing allotment.
B. Burn grasslands regularly.
C. Establish a regional ecological restoration plan and restore
riparian habitats to their former structure.
D. Prohibit wholesale clearing of native vegetation for exotic
pasture grass planting for livestock.
E. Retain and protect willows and cottonwoods recruited after
catastrophic floods.
F. Keep cattle out of riparian areas during periods of willow
and cottonwood seedling establishment.
G. Limit groundwater extraction where it is greater than annual
recharge rates.
H. Eliminate dams and other artificial water impoundments that
have silted-in wherever there is a capacity for streams to flow
uninterrupted again.
1. Limit flood control and artificial channelization engineering
schemes to only those areas where human welfare is directly and
frequently affected.
J. Prohibit plantings of exotic species or ecotypes along highways
and along irrigation canals.
K. Limit any cutting of mesquite or ironwood to pruning by handaxes,
and avoid any chainsawing of these trees below 1 meter aboveground.
L. Manage irrigation tailwaters and primary-treated sewage to
restore the wetlands of the Colorado River delta.

"Let us assume that the next stage in the West will not be
a mere continuation of the present. What then might we expect? What
should we work for? Now no one could reliably predict a detailed
blueprint for a posthydraulic society ...But one could confidently
say that there are certain general strategies the West is going
to have to pursue if it wants to find its way toward a more open,
free, and democratic society. Those strategies must begin with a
new relation to nature and a new technics."
-Donald Worster
Rivers of Empire (1985)
"Desert residents are using more water than is being replenished
into the region's water supply accounts. If this 'deficit spending'
continues, the available non-renewable supplies of water will eventually
be depleted. We owe it to future generations to carefully consider
the choices we make today in where and how we use our precious desert
waters... [While] individual action in conserving water is critical,
...it is not enough. We also need to support conservation efforts
on a larger scale. For example, working together we can raise awareness
about the critical importance of riparian habitats to the future
health of Sonoran Desert ecosystems [from] promoting laws and regulations
that protect the existing flows of streams and washes, to championing
planning and zoning regulations that preserve sensitive riparian
areas and native vegetation."

Demands (1997)
"Probably more than 5% of [North American] lands and waters
are overrun by the most aggressive of the more than 2000 species
of exotic or alien plants [including] nearly 200 of approximately
250 National Park Service units [and] 60% of The Nature Conservancy's
preserves ...[We must] support proposals by resource managers to
address species invasions. Proposals to combat weeds or, especially,
introduced mammals, often generate opposition from people who do
not understand the environmental cost paid for allowing the newcomer
to remain... Remember we have forfeited the 'easy' solutions when
we failed to halt these invaders ...or when we first became aware
of their presence. Now we have to face the need to use more drastic
measures."
