The Tree Lichen, if left undisturbed, can continue to survive for at lesat 100 years. Some species of Lichens found in remore areas of the Tundra and Antartic have been carbon dated and shown to be over 8000 years old!
The ability to grow after years of no rain is a special feature of a Lichens- damaged DNA must be repaired efficently too which is another faeture of the Lichen symbiotic life style.
Average life span in the wild is 10-24 years. The eldest British bird known was 31 years, 10 months and 29 days old in 2007 (British Trust for Ornithology).
Being a flowering plant I grow by colonising soil with seed. I tend to germinate from seed in the spring, grow vigorously to produce flowers and then set seed, and die back in the winter. Therefore, I am generally an annual as I complete my entire growth cycle in one growing season. However, if conditions are particularly cold and harsh in the spring I may only produce flowers and seed in the 2nd growing season and then complete my growth cycle, in whic case I am a biennial.
when I am in and egg stage I can live up to 3 years without hatching if the conditions aren’t right for it. At a naiad stage (as a larva) I can live up to 3 months,and then I transform into an adult damselfly and I in this stage my main aim is to reproduce and I can last up to 2 months.
