Property Damage
Even with all the other damage being caused by vehicles, trails and roads, garbage,
human feces, and forest fires, the damage does not end there.  Property damage as
well is high on the scale of actions that happen by illegal aliens on a day to day basis
and cost tax payers funds to correct.

International fences are repeatedly cut or torn down in many locations along the
Mexico/United States borders.  Interior fences also are cut and damaged allowing
unauthorized cattle and off-highway vehicles and even cattle rustlers to steal cattle
taking them back to Mexico.  This brings additional problems and threats to
livestock operations as Mexican livestock is often not vaccinated and therefore can
bring diseases to United States cattle.

Gates are left open or rammed, security locks are cut, signs are driven over and
heavy damage or destruction to water developments or other improvements occur
regularly. These open gates permit unauthorized Mexican livestock to use Federal
lands, damaging endangered species habitats.

Recreational, cultural and administrative sites are repeatedly vandalized and
damaged.

Breaking and Entering and Burglaries
B&E's and Burglaries along the border are common and include everything from
historic and government structures, employee and private residences, to
residences and businesses on reservation lands.  Money, firearms and other
personal items have all been taken from employee or private residences on Federal
and Private lands.  Even vehicles have been vandalized or stolen.

In San Bernardino National Wildlife Refuge alone.  A concrete and metal
maintenance shop was removed due to being broken into numerous times resulting in
thousands of dollars worth of stolen equipment. A government dump truck was
stolen and driven through a cut border fence into Mexico, and vehicles owned by
both refuge and public have been forcibly entered and damaged in attempts to
steal them.

Two homes in Tubac area were broken into and two rifles stolen.  These rifles
were then used to murder two employees of the Salerno Ranch.

Homes near border are repeatedly ransacked for canned goods and water.  Those
not ransacked directly are harassed by illegal aliens seeking water, medical
supplies, food or shelter.

Non-Native Plants
Illegal aliens in significant numbers present an increased risk of transporting alien,
invasive species from their home areas and establishing them on Federal lands.
Weed seeds of many varieties are easily transported on clothing.  Salt ceder,
Lehmann lovegrass, bufflegrass, cheatgrass, and other invasive species are all
spreading in this manner.  Water bottles filled at various locations in wetlands can
infect otherwise protected Federal wetlands with invasive parasites and diseases
which can doom native fish and wildlife.  Asian tapeworm has eliminated or
impacted some populations of Federally-listed threatened and endangered fish.  
Chytrid fungus from South America was first documented at San Bernardino
National Wildlife Refuge.  This fungus is deadly to amphibians and helped lead to
elimination of Chiricahua leopard frogs from the refuge.
Still more damage is done....

BUFFLEGRASS
Bufflegrass is spreading rapidly
across the Sonoran Desert.  Once
established, bufflegrass displaces
native vegetation and forms dense,
single-species strands. Where
dense enough it can carry fire into
the Sorroan Desert vegetation,
which have no natural adaption to
fires.
Sorghum Halepense

Extremely invasive noxious weed.
High seed production and difficult
to eradicate. Toxic to grazing
stock, host for crop pathogens,
high fire risk, reduces soil fertility
and known allergen.
