Amphibians on the rise in The Netherlands

European tree frogFrom Dutch news agency Novum:

The numbers of frogs and toads in The Netherlands are on the rise, though worldwide there is a decline.

The numbers are from the Centraal Bureau voor de Statistiek (CBS) between 1997 and 2004.

Ever since the 1950s, there was a decline in The Netherlands of the numbers of frogs and toads.

According to the people doing the research, this growth is due to improvement in water quality and digging of new ponds.

They say the number of tree frogs is rising fastest.

Since 1997, there are four times as many European tree frogs.

The numbers of common and edible frogs in The Netherlands are said to rise with five percent a year.

The yellow bellied toad is still threatened, though numbers are on the rise, according to the CBS.

Numbers of common toads rose with 3.5 percent a year.

    Thanks to Michael Bean, the largest frog species on the West Coast may stage a comeback in the most unexpected habitat – the private grounds of a leading California winery. The California red-legged frog is among the many species to benefit from the Safe Harbor Agreement, a program in which private landowners maintain habitats for endangered species and, in return, are guaranteed against federal restrictions on their land. Bean has dedicated his career to forging programs like this and shaping wildlife law. On May 24, he will speak about the imminent challenges facing the Endangered Species Act in Congress and the potential impact on over a thousand rare plants and animals.
