CONIFEROUS TREES
|
|
Reproduction
- By growing seeds inside of cones.
- Two types of cones are produced on the same tree:Staminate Cone (male:contains pollen) and Ovulate cone(female cone:catches the pollen and where the seeds grow and mature)
- Pollen from the male cones is transferred to female cones that contain the ova
- When the seeds are matured the cones open and the seeds are dispersed.
Adaptations
- Leaves are long and thin, often called needles.
- Needles don't remain on conifers forever. A few species lose them every fall.
- Needles of other conifer species remain on the plant for 2-14 years.
- Needles of other conifer species remain on the plant for 2-14 years.

Pine Tree
Identification Of Pine Tree
According to the Tree Book of BC the shape ,needles clearly tells me that is Pine Tree. This photos was not took in the forest but in neighbor .I am not sure which Pine it is as pine has different species. I am more likely thinking it may be yellow Pine. I have also learned in my research that Pine Tree is a native conifer of BC. From my observation in Byrne Creek forest I don't think that pine Tree is native to the forest because I haven't saw a lot of them and the ones I saw mostly was people's yard. Also the way it was planted this makes me think that it was brought over by someone .
