Wildlife Rescue

By Thembi Borras

Have you ever been frantic, not sure what to do, having encountered an animal you thought injured, abandoned or in need of attention? I have, last year I was introduced to a bird in a downed nest. This circumstance effected me to seek assistance from the wildlife rescue community. Before you engage this limited resource community there is information that will better inform your decision to walk away, care for the species yourself or bring it to a rescue facility.

Locally, all wildlife is born in the spring, in particular the month of May. May is the month for babies. You may think a fawn needs attention, because you conceive it has been abandoned, not seeing its mother nearby. In fact the mother, on purpose, remains distant from the fawn to protect it as she is scented and the fawn is not. If you encounter a fawn, don't pick it up and keep your dogs on a leash, during this time of year, to prevent an unnecessary dog/ fawn encounter.

If you find a baby bird, owl or hawk out of the nest it is important to know the parents will likely continue to care for it, especially owls. If you are able to reach the nest safely, put the bird back in its nest. It is a myth that the parents will abandon their young if they detect human scent, in fact birds have a poor sense of smell. If a nest is down, you can put it in an open cardboard box and nail the box to the tree then put the young in the nest. Stunned birds found near windows may need nothing more than a cardboard box in a safe location in which to recover.

If the animal is obviously injured, evidenced by a drooping wing or blood, local veterinarians may treat wildlife at no charge. At a minimum, veterinarians will have referral numbers for wildlife rescue facilities. If possible, call your veterinarian or one of the rescue facilities prior to removal as they may be able to guide your decision and advise in proper transport procedures. Sonoma Wildlife, a mammal rescue facility can be reached at 707-544-6713. Bird Rescue of Santa Rosa, a bird rescue facility, can be reached at 707-523-2473. Willits Wildlife Rehabilitation Team, a local non profit wildlife rescue facility, can be reached at 707-459-9539 and donations for the care of injured wildlife can be sent to POB 44, Willits, CA 95490.

The bulk of this production was gleaned from a phone conversation with Ronnie James of Woodlands Wildlife a small local rescue facility that receives all referrals through local veterinarians. Woodlands Wildlife, a non profit, will receive donations for the care of injured wildlife at POB 1336, Mendocino, CA 95460.

Redwood Top Die-back

By Thembi Borras

Throughout the redwood region redwood tops occasionally dieback. A green live top will turn brown, lose its needles and all that remains is a brown stem and lateral branches. The tree may or may not grow another top from this persistent weak spot. The dead top will sometimes break out and the tree becomes a flat top. Trees with dead tops are prevented from growing taller unless a new top grows, regardless the tree will continue to grow in diameter.

There are different causes of redwood top dieback, along the coast the harsh salt laden winds can cause tops, especially those that stick up more prominently, to lose their needles and dieback. Between Eureka and Crescent City, in the vicinity of the Drury Bypass, bear damage is apparent. Bears do not appear to get to the top, but will shred the bark, where the tree bole is larger. If the damage is extensive, the entire tree including the top will die. In Humboldt Redwoods Sate Park just south of Scotia, evident on the Eel River side of Highway 101 are old-growth redwood where nearly every tall tree has a dead top. In this case, the highway changed the water drainage pattern and increased the exposure of the treetops to increased air movement. Increased water stress combined with desiccation may have caused the tops to die.

The most common cause of redwood top dieback is animal damage by tree squirrels, wood rats and the occasional porcupine, which can chew the bark to the cambium. If enough area is affected the flow of nutrients is disrupted and the portion above the damaged area will die. The species of squirrels most likely causing the damage are Douglas' Squirrel (Tamiasciurus douglasii), also called "Red Tree Squirrel" or "Chickaree" and to a lesser extent the Western Gray Squirrel (Sciurus griseus), also called the "California Gray Squirrel". Dusky-footed Woodrats (Neotoma fuscipes) also cause damage, in younger redwood trees, trees less than 20 feet in height. In a clump of a dozen trees, the woodrat may advance a handful of tops to die. A handful more may be lightly chewed and the balance may escape being munched altogether. You may be able to catch the tree squirrels in action as they are active during the day, but it will be harder to catch woodrats in action as they are nocturnal.
