For 15 consecutive seasons the number of wild orchids growing in an
area of Gentofte
Municipality north of Copenhagen, Denmark,
was counted and registered. The area covers only about 0.2 square kilometres,
but includes a variety of habitats, such as the edges of a lake, wet
sunny meadows, small darker woodlands (with alder, birch or willow),
patches of bog moss, as well as difficult accessible marshy spots.
In the period studied, three new species have been found: In 1990 Dactylorhiza
maculata ssp. fuchsii was seen for the first time, and the
first observation of D. majalis ssp. praetermissa was
done the year after. Besides this, since 1992, low plants of D. purpurella
have been recorded. In 2000, possible Dactylorhiza-hybrids were
Unlike most of the other orchids, a plant of Corallorhiza trifida
may live underground for several years, but may also flower at least
two years in succession.

In the present season which started early April and probably will last
until October (when the final counts of Epipactis helleborine
notoriously are to be done), the 2001-column of the tables will be updated
at least weekly.
