Speaker was introduced. Jim Cardoza is a wildlife biologist with Massachusetts
Fish & Wildlife. He has spend 36 years in activities surrounding
wildlife, specifically black bear and turkey. Some features of his
talk include:
*There are 3 departments: Fisheries, Natural Heritage
(rare & endangered), and Wildlife
*Beaver were extirpated in the state around the time of
the Revolutionary War, now widespread in SE MA & elsewhere in the state
*Turkey were common during colonial times but disappeared
by 1851 and reintroduced in the 1970’s
*Jim illustrated land use changes through time and the
effects this had on wildlife. From 1750 to 1850, people increased while
bears decreased. Deer, once numbering in the 70-80,000, were estimated to
be only 5,000 in 1850’s. Now, they are numerous again, in Boston and
everywhere.
*Regarding bears, biologists seek to find out status,
depredations, habitat. Jim reviewed culvert traps, Aldrich bear snare
which is illegal now since 1996, and the use of bear hounds. They do
not tranquilize bears. They use a cocktail of drugs to restrain bears during
a workup. Researches use the 1st premolar tooth to age a bear.
2 oldest reported in the state is a 25-26 year old male and an equally old
female. He’s heard of a 33 year old bear.
*Biggest bear recorded 520 pounds. Usually 225-325
for male bears in MA
*Male bears have 10x the home range of females, which
overlaps several females’ ranges. Males disperse, females don’t.
Mating occurs in July. Females have delayed implantation. Cubs
from the same litter may have different fathers. A brush pile den is
common in MA.
*Bears west of the CT river average about 1bear/sq. mile
of forest. Cub survival ils 53%; average litter size: 2.3; Breeding
interval: 2 years; sexual maturity reached at 3-3.5 years old; males experience
higher mortality when cubs.
*estimated bear population: 1982:
500
1998: 1800
now: 3,400
*From 1900 to date, 55 humans have been killed by
black bears – usually predatory bears.
The evening concluded as usual with delicious snacks, visiting with our guest
speaker and socializing.
