    Traveling across the state, you soon discover that Oregon is home to a wide range of trees. There are 30 native coniferous species and 37 native species of broadleaf trees. Oregon varies greatly in terms of elevation, temperature, wind, rainfall and soil composition. Combinations of all these factors help determine the dominant tree species of an area.   Seed Dispersal Lesson PowerPoint, Plants, Wind, Water, Animals, Ecology 7, views.

The seeds float then wash up and germinate.

It entrusts us with its seed, while surrounding it with the gift of fruit, as prepayment for conscious seed dispersal; the tree trusts us to do the right thing and care for its seeds as best we are able, by at least letting each one. A good book to get some basic concepts pertaining to plants, farming, agriculture, seeds and the like. Doesn't give much detail but covers a lot of broad topics. Pictures are great. 3 year old loved looking at the pictures and talking about the text/5.

This plant has a mace-like section consisting of thousands of tiny tightly-packed fruits. As the picture shows, little tufts on the fruits allow the seeds to be transported when the time comes.

In southwestern Oregon and northwestern California, grand fir is common in mixed evergreen and conifer forests, where it is associated with Shasta red fir (Abies magnifica var. shastensis), noble fir (A. procera), redwood (Sequoia sempervirens), western hemlock, Sitka spruce, and coastal Douglas-fir [2,].

Additionally, students could watch a video on dispersal, play an online game, and have a choice of a wide range of projects to illustrate their mastery of.

The purpose of this study was to investigate seed dispersal and germination of seeds in the soil as factors in establishment of big sagebrush seedlings.

Seed dispersal began at seed maturity in December. Under the shrub canopy the dispersal of seeds was greater to the east. Between shrubs the dispersal of seeds tended to be uniform.

For 6 months of each year there were no detectable germinable. A median dispersal distance of 31 m was determined for filled seeds based on direct assignment of seeds to their mother trees. This was higher than that determined in the previous studies using different methods.

Dispersal distance was negatively correlated to seed-weight, but this was partially compensated for by the length of seed by: Seed Dispersal. How Plants Spread. Before they can grow into new plants, seeds need to leave the seed pod.

If all the seeds a plant produced landed just underneath the parent plant, they would be too crowded, and the established large plant might not leave them enough light or water for them all to develop properly. indicate that red maples continue to recruit into the adult portions of populations throughout the remainder of the old field successional sequence in this region (Peet and Christensen, ).

Seed dispersal began at seed maturity in December. Under the shrub canopy the dispersal of seeds was greater to the east. Between shrubs the dispersal of seeds tended to be uniform. For 6 months of each year there were no detectable germinable.While animals and wind have been proposed as agents of seed dispersal for Daucus carota, a common weed, no quantitative data can be found in the literature to support either.

This paper presents evidence to support both modes of dispersal. Seeds attach to fur coarser than that of rabbit, and also disperse by wind. Spines appear to facilitate both mechanisms.
