Is lupine native to Oregon?
Today, Oregon Lupine is found predominately in the Willamette Valley of Oregon, where it occupies native grassland habitats. There, Oregon Lupine occurs in native upland prairies and open oak woodlands on soils that are mesic (normal) to slightly xeric (dry).
What is long distance dispersal?
Long-distance dispersal is a characteristically extreme event of propagule movement in any plant or animal population, typically occurring with an extremely low probability but potentially reaching an extremely long distance.
Do bears eat lupine?
Some landscaping trees, bushes, and flowers that are considered not attractive to bears include willows, penstemon, mock orange, lupine, and columbine. For orchards, protect with fencing and keep a clean orchard.
Where is Lupine Oregon?

How far can a seed travel by wind?
Despite this, the distance a seed can potentially travel will vary by several orders of magnitude, and therefore seeds do have the capacity to travel huge distances. Storms have been found to enable seeds of poplar to travel up to 30km, maple 4km, scots pine 2km, birch 1.6km, and ash 0.5km.
What is passive dispersal?
Passive dispersal involves both plants and animals that cannot themselves move but use dispersal units called disseminules to aid in reproduction or the exploitation of new habitats.

What are hitchhiker seeds?
What are Hitchhiker Weeds? Weed seeds spread in a variety of ways, whether traveling by water, by air, or on animals. The group of weeds nicknamed the “hitchhikers” are seeds that stick to clothing and fur, making it difficult to dislodge them immediately.
What is secular migration?
(3) Secular migration is diffusion taking place so slowly that the diffusing species undergoes appreciable evolutionary change during the process. The range of the species expands or shifts over long time intervals (thousands or millions of years).
What is niche overlap?
Niche overlap describes the situation in which co-occurring species share parts of their niche space with each other. High niche overlap may lead to conflictual interactions (such as competition and exclusion) for some species ( Giménez Gómez et al.
