Action plans

These species, a group of about 150 ground-dwelling gamebird, are found on every continent apart from Antarctica. They live in a wide variety of habitats from tropical forests, high-altitude alpine zones, temperate forests, open country, to desert environment. Although widespread, little is known of the species occuring outside Europe and North America, but several species are considered at grave risk of extinction. Since publication of the first action plan in 1995 a large increase in the amount and quality of conservation work has taken place.

In the five years since publication of the 1995-99 action plan, the Megapode Specialist Group has been active in promoting, initiating and executing conservation and research projects on thermometer birds. But the conservation outlook for many species remains bleak. Their habit of nesting on or near beaches, often on small islands, make them vulnerable to disturbance and egg-collection, and several species are greatly threatened. The greatest threats are over-exploitation of their eggs, loss of forested habitats, and introduction of predators.

As large ground-dwelling birds, pheasants are widely hunted for food, plumage and the live bird trade - consequently many species are threatened. They are largely dependent on forested habitats, making them highly vulnerable to deforestation and habitat degradation. The first edition covered 1995-1999, and many of its recommendations have been addressed. This new edition provides an update, including a new set of conservation projects with international priority for initiation during the period 2000-4.

Bryophytes are of great importance in their ecosystems and for human well-being. They stabilise soil crust through colonisation of bare grounds and rocks; they are essential in nutrient recycling, biomass production, and carbon fixing; they control water through an effective retention mechanism; and they have economic value as peat for fuel, horticulture, oil absorption, and as sources of a wide variety of chemical compounds. Bryophytes have long been used for medicinal purposes and provide a food-source for reindeer, geese, ducks, sheep, musk-ox, lemmings, and other rodents.

The West Indian Iguanas form a unique group of species inhabiting tropical dry forests throughout the Bahanas and the Greater and Lesser Antilles. They are among the most endangered of the world's lizards, primarily because much of their fragile island habitat has been eliminated by human developemnt or severely degraded by exotic species. The Jamaican iguana, considered by some to be the rarest lizard in the world, may number no more than 100 adults.

Grouse have long attracted and fascinated people. Their display behaviour, and their traditional communal mating grounds or "leks", have inspired poetry and folklore as well as scientific theories on sexual selection and mating systems. Im many parts of their range, hunting plays a major role in the culture, economy, and subsistence of local communities. Although from a global perspective their status is not critical, grouse are far from being safe, and on a local scale, many local populations of grouse are declining and threatened with extinction.
