Ponderosa Pine The Pine Family–Pinaceae Pinus ponderosa C. Lawson (PIE-nus pon-der-OH-suh) Names: Our 3-needled pine is the Ponderosa Pine, sometimes called the Western Yellow Pine. For most of us who grew up in the 60’s and 70’s the word “Ponderosa” elicits memories of Hoss and Little Joe Cartwright, characters in the TV show Bonanza. The [ ]. This is Lesson 3: Seed Dispersal, from Unit 3 (How Plants Work) in a series of units on plants, animals, and ecosystems. It includes many NGSS correlations for disciplinary core ideas, crosscutting concepts, and science and engineering practices for the lessons, but not all are addressed explicitly in this lesson.
Noble fir, known for its beautiful symmetrical appearance, is a tall conifer species found in the Pacific coastal ranges of North America at an altitude of , m (3,, ft). It has long and pointy leaves that turn upward, revealing the branches below. When young, the tree has smooth, gray bark with resin blisters; but [ ]. Click on the title to browse this issue.
Seed dispersal and germination were examined for 70 species from the cold Gurbantunggut Desert in northwest China. Mean and range (3 orders of magnitude) of seed mass were smaller and narrower than those in other floras (5–8 orders of magnitude), which implies that selection favors relatively smaller seeds in this by: 7.

The coincidence of large seeds in semi-arid habitats repeats the pattern seen in animal-dispersed pines, suggesting that this species might be dispersed, in part, by seed-caching by: Douglas-fir (Pseudotsuga menziesii) (click on each photo to enlarge image) Needles: About 1" long with a blunt tip.

The coast redwood is the world's tallest tree, but the coast Douglas fir (Pseudotsuga menziesii) is a close second, with the tallest specimens reaching heights.
The only available study about seed dispersal in Dabieshan white pines (Su et al., ) reported that only two forest rodents were found to feed on the seed, and we therefore speculate that birds.

Viability: Commonly, less than 40 percent of coast Douglas-fir seeds are sound. Seed soundness decreases during poor seed crop years. During poor cone production years in northwestern California, old-growth Douglas-fir seed soundness averaged 18 percent, while seed soundness was 53 percent in a year-old western Washington stand.

Uses Ethnobotanic: Douglas-fir needles were made into a tea and drank by Isleta Puebloans in New Mexico to cure rheumatism. Douglas-fir resin was used by the Shasta in northern California to poultice cuts and the Yuki along the California coast used a decoction.
In this method of seed dispersal, seeds float away from their parent plant. These are mainly seen in those plant which lives in water or nearby the water bodies like beaches, lakes, ponds etc. Coconut, palm, mangroves, waterlily, water mint, are a few examples of plants whose seed.
