The length of life for a tree depends upon so many things. The climate conditions (water, temperature, sunlight, etc.), fire dangers, the type of tree, and the condition of the soil are all things that help determine how long a tree will live. So, the true answer is ... it depends! I can tell you that the oldest living tree is a bristlecone pine tree called " Methuselah". It is currently 4,767 years old! See similar questions...

Live trees are sometimes removed from park land if, once inspected by our Forestry Crew, it is determined that the tree may pose a threat to the general public or adjacent structures. See similar questions...

Well I guess that depends on who you talk to--Most farmers who are in the egg producing business will say 2 years. Those who are in the meat producing business will say 6 months--Those who keep birds as pets (with names) or who are not interested in maximum production of eggs, will find that chickens can live up to 8 or 10 years.

The Arbor Day Foundation does not condone the practice of tree topping. Topping creates many problems for trees including insect infestations and diseases, weak limbs, shock and starvation to the tree and poor aesthetic qualities. For more information on tree topping, please contact Member Services for Tree City USA Bulletin #8 "Don't Top Trees". This bulletin is available for $3. See similar questions...

You'd think that would be a simple question, with a simple answer. Unfortunately, every source I've found gives different information: Britanica Online says the lifespan of a domestic cat in captivity is 21 years (in context, this seems to be the maximum age of the vast majority of otherwise healthy cats!!!). The Tidycat website once indicated that the average Russian Blue lives 18 years (I couldn't find a reference to persian lifespan). On the HomeArts Ask the Vet website, Dr. See similar questions...

Mono Lake Brine Shrimp have two to three generations every year, and they live for up to 6 months. They all die off by the end of the year as the water cools. Cysts hatch the following April and the cycle repeats. Click here for more on Mono Lake Brine Shrimp. top See similar questions...

Head lice live about a month after hatching. It takes about a week for an egg to mature and hatch. The nymph louse grows to maturity in about a week to ten days. This leaves about three weeks of active life in the hair. See similar questions...

The average life span of most giant breeds is about 8-10 years. I know of Danes living to 10-12 years, but right now unfortunately that is the exception rather than the rule. There are a few health problems which afflict the Great Dane breed: growth problems (HOD, PANO and OCD), hip dysplasia (OFA and Penn-Hip tests), and bloat/GDV/torsion are primary concerns. Wobblers, thyroid problems, and problems with the eyes (CERF test) also appear in the breed. Se our HEALTH links for more info: See similar questions...

Bees live for 6 weeks when gathering nectar during the summer. Their wings gradually wear away from constant activity. Those that are alive in the later fall live till spring and care for the larva hatched from eggs laid in late winter. These worker bees die before the honey flow starts again in the spring. The queen bee can live for 3-4 years. See similar questions...
