Birds as indicator
species
A farm with a rich diversity of birds will also have a relatively
high diversity of trees, shrubs, mammals, reptiles, frogs and invertebrates.
For this reason birds are recognized as 'indicator species', their
presence indicating the presence of many other species, and thus
the environmental health of the farm.
Remnants
is a game where players describe the land use and environmental
attributes of a farm in Australia's temperate woodlands. The program
then describes how these attributes influence biodiversity on and
around the farm. Remnants is not detailed enough to apply to any
specific farm, but the rules that determine the final score are
based on the results of the Birds on Farms Survey.
The Birds on Farms
Survey
The results presented by Remnants are
based on a two-year survey of birds on 330 farms in southern and
eastern Australia, between 1995 and 1998. Specific management recommendations
are also based on other research and expert opinion.
The average
farm size was 608 ha (excluding the ten largest farms), and most
were sheep, beef or wheat-sheep properties. Around 500 volunteers
participated in the surveys, mostly farmers or people working with
farmers (76 per cent). A more extensive report, outlining the methods
and describing the results of the Birds on Farms survey, is available
from the Birding Shop.
Playing Remnants
Remnants will perform best when used with versions of Internet Explorer
or Netscape Navigator later than 4.0.
The first Remnants
question asks you to name your imaginary farm, while the remaining
questions are all answered by selecting an option from the pull
down menus. Detailed information is available for many of the questions,
simply click on the "More info" icons and the information will appear
in pop-up windows.
After you hit
the 'Get Results' button your results will appear in a new window
from where the text can be printed or saved.
