Describe the damage done by pocket gophers in field crops -
ANSWERS-they feed on the roots of field crops, plants with large
taproots are the most susceptible
Describe the damage done by ground squirrels in field crops -
ANSWERS-they will eat field crops in their seedling stage
Describe the damage done by carnivores to drip irrigation lines -
ANSWERS-drip lines will have the appearance of having been
compressed and shredded as if chewed by dogs
Describe the damage done by rodents to drip irrigation lines -
ANSWERS-the drip lines are scraped or gnawed repeatedly and often
shows evidence of the presence of paired incisor tooth marks
List the bird pests that damage and cause problems in aquaculture
facilities - ANSWERS-gulls, herons, kingfishers, terns
List the bird pests that damage and cause problems in buildings and
other structures - ANSWERS-house sparrows, pigeons, swallows
nesting in or on structures

Describe the habitat of crows - ANSWERS-Forests, farmlands, river-
bottoms, shores, parklands, urban areas. Crows sometimes select urban
roosting sites after the breeding season and through the winter period
Describe the habitat of ground squirrels - ANSWERS-S. beldingi
inhabits meadows and green fields or along their edges. S. beecheyi lives
on natural rangeland, pastures, grain fields, slopes with scattered trees,
and rocky ridges. It avoids thick chaparral and dense woods
Describe the habitat of horned larks - ANSWERS-Grasslands, meadows,
prairies, stony deserts, and tundra are preferred habitat. Open fields of
cultivated or irrigated crops in California are invaded after the natural
vegetation dries up in summer.
Describe the habitat of house finches (linnets) - ANSWERS-Open
woods, scrub-growth areas, deserts, ranches, farmlands, suburbs, and
towns. Human development has created extensive favorable habitat i.e.
hedgerows, field edges, and crop fields
Describe the habitat of meadow voles - ANSWERS-They are likely to
be found where there is good vegetative cover. They generally do not
invade cultivated crops until the crop is tall enough to provide food and
shelter. They are historically found in marshy ground, saltwater and

fresh wet meadows, and dry grassy hillsides. They are also found in any
agricultural crop that provides sufficient cover and food.
Describe the habitat of moles - ANSWERS-They make their home
burrow in high dry spots but 'hunt' in cool, moist soil where their food
preferences are more plentiful. The home burrows are often found under
large trees, buildings or sidewalks
Describe the habitat of pocket gophers - ANSWERS-Many agricultural
and residential properties are ideal habitats and given the abundance of
vegetation associated with regular irrigation and relatively deep, friable
soils
Describe the habitat of rabbits and hares - ANSWERS-Black-tailed
jackrabbits occupy open grasslands and sparsely vegetated deserts in the
CA valleys and foothills. Desert cottontails are abundant in grasslands,
open forests, and desert shrub habitats. They also readily utilize human-
altered habitats, particularly where different habitat types are juxtaposed.
Brush rabbits prefer brushy areas where vegetative cover is dense. This
includes early successional oak and coniferdominated landscapes,
riparian areas, or areas with abundant brambles, vines, or thickets.
Describe the burrows and mounds of ground squirrels - ANSWERS-they
average about 4 inches in diameter, and individual burrows are 5 to 30
