Habitat Conservation Plan
A Habitat Conservation Plan (HCP) is a required part of an application for an Incidental Take Permit, a permit issued under the United States Endangered Species Act of 1973, Endangered Species Act (ESA) to private entities undertaking projects that might result in the destruction of an endangered or threatened species. It is a planning document that ensures that the anticipated take of a listed species will be minimized or mitigated by conserving the habitat upon which the species depend, thereby contributing to the recovery of the species as a whole. Background The importance of preserving rare species was legally recognized in 1973 when the Endangered Species Act (ESA) was signed into federal law. The purpose of the ESA is not only to protect species that have been listed as threatened or endangered, but also to Environmental protection, conserve the ecosystems upon which those species depend. In aiming to protect species in danger of becoming extinct, the ESA prohibits actions th ...

''Polyphylla barbata'' is a rare species of beetle known by the common name Mount Hermon June beetle. It is endemic to California, where it occurs only in Santa Cruz County. There is only a single occurrence of the beetle on a stretch of territory of under . This is a federally listed endangered species of the United States.''Polyphylla barbata''.
The Nature Conservancy.
The beetle is about 2 centimeters long, black and brown in color with broken white longitudinal stripes on the back. The are covered in a thin coat of hairs. The female is slightly larger than the male. The female spends most of her time underground, coming out only to mate with the male.

Spawning
Spawn is the Egg cell, eggs and Spermatozoa, sperm released or deposited into water by aquatic animals. As a verb, ''to spawn'' refers to the process of freely releasing eggs and sperm into a body of water (fresh or marine); the physical act is known as spawning. The vast majority of aquatic and amphibious animals reproduce through spawning. These include the following groups: *Bony fishes *Crustaceans (such as crabs, shrimps, etc.) *Mollusks (such as oysters, octopus, squid) *Echinoderms (such as sea urchins, sea stars, sea cucumbers, etc.) *Amphibians (such as frogs, toads, salamanders, newts) *Aquatic insects (such as dragonflies, mayflies, mosquitoes) *Coral, which are living colonies of tiny, aquatic organisms—not plants, as they are sometimes perceived to be. Corals, while appearing sedentary or botanical by nature, actually spawn by releasing clouds of sperm and egg cells into the water column, where the two mix. As a general rule, aquatic or semiaquatic reptiles, ...

Coho Salmon
The coho salmon (''Oncorhynchus kisutch;'' Karuk: achvuun) is a species of anadromous fish in the salmon family (biology), family and one of the five Pacific salmon species. Coho salmon are also known as silver salmon (or "silvers") and is often sold as medium red salmon. The scientific species name is based on the Russian language, Russian common name ''kizhuch'' (кижуч). Description During their ocean phase, coho salmon have silver sides and dark-blue backs with spots on their back and upper tail lobe. During their spawning phase, their jaws and teeth become hooked. After entering fresh water, they develop bright-red sides, bluish-green heads and backs, dark bellies and dark spots on their backs. Sexually maturing fish develop a light-pink or rose shading along the belly, and the males may show a slight arching of the back. Mature adults have a pronounced red skin color with darker backs and spots, with females having darker shades than males. Coho salmon average 20 to ...

Nest
A nest is a structure built for certain animals to hold Egg (biology), eggs or young. Although nests are most closely associated with birds, members of all classes of vertebrates and some invertebrates construct nests. They may be composed of organic material such as twigs, grass, and leaves, or may be a simple depression in the ground, or a hole in a rock, tree, or building. Human-made materials, such as string, plastic, cloth, or paper, may also be used. Nests can be found in all types of habitat. Nest building is driven by a biological urge known as the nesting instinct in birds and mammals. Generally each species has a distinctive style of nest. Nest complexity is roughly correlated with the level of parental care by adults. Nest building is considered a key adaptive advantage among birds, and they exhibit the most variation in their nests ranging from simple holes in the ground to elaborate communal nests hosting hundreds of individuals. Nests of prairie dogs and severa ...

Marbled Murrelet
The marbled murrelet (''Brachyramphus marmoratus'') is a small seabird from the North Pacific. It is a member of the family Alcidae, which includes auklets, guillemots, murres and puffins. It nests in old-growth forests or on the ground at higher latitudes where trees cannot grow. Its population has declined since humans began logging its nest trees in the latter half of the 19th century. The decline of the marbled murrelet and its association with old-growth forests—at least in the southern part of its range—have made it a flagship species in the forest protection movement. Taxonomy The marbled murrelet was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the grebes and loons in the genus '' Colymbus'' and coined the binomial name ''Colymbus marmoratus''. Gmelin based his description on the "marbled murrelet" that had been described and illustrated in 1 ...

Northern Spotted Owl
The northern spotted owl (''Strix occidentalis caurina'') is one of three spotted owl subspecies. A western North American bird in the family Strigidae, genus ''Strix (genus), Strix'', it is a medium-sized dark brown owl native to the Pacific Northwest. An important Bioindicator, indicator species, the northern spotted owl remains Threatened species, threatened due to continued population decline from human-caused habitat destruction and competition with invasive species, its main competitor being the barred owl. Description Northern spotted owls have dark brown plumage with white spots and no ear tufts. They are typically around sixteen to nineteen inches in length and one to one and one sixth pounds. They have a round facial disc that is dark brown with a visible "X" between their eyes. Females are about 10-20% larger than males. Their wingspan is approximately 42 inches. They are a mainly nocturnal species, and form long-term pair bonds. While most owls have yellow to red- ...

Old-growth Forest
An old-growth forest or primary forest is a forest that has developed over a long period of time without disturbance. Due to this, old-growth forests exhibit unique ecological features. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. One-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitats that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree heights and diameters, and diverse tree species and classes and sizes of woody debris., the world has of primary forest ...

Headwaters Forest
The Headwaters Forest Reserve is a group of old growth coast redwood (''Sequoia sempervirens'') groves in the Northern California coastal forests ecoregion near Humboldt Bay of the U.S. state of California. Comprising about , it is managed by the Bureau of Land Management (BLM) as part of the National Landscape Conservation System. The climate is characterized by maritime conditions of cool, wet and foggy winters and cool to warm cloudy summers. Elevations range from to over . Overview The reserve was established in 1999 (H.R. 2107, Title V. Sec.501.) The reserve was created after a 15-year effort to save the ancient ecosystem (with some trees estimated at over two thousand years old), from being clearcut. This reserve of is public land and is under the stewardship of the US Department of the Interior, Bureau of Land Management (BLM). Of the total area, are old-growth redwood stands, surrounded by of previously harvested timberlands. These were included in the purchase ...
