Bijzondere vondsten van sieralgen in een terrasvijver in Lier (België, provincie Antwerpen)

Remarkable finds of desmids in a terrace pond in Lier (Belgium, province of Antwerpen) Investigating the presence of desmids in garden ponds seems somewhat unusual. However, it can yield remarkable discoveries. Often, these ponds are left untouched for extended periods, which promotes the undisturbed development of a varied micro flora. Desmids can accidentally hitch-hike on aquatic plants brought in from nature or pond centres. In the village of Lier (Belgium), the author examined a small garden pond that is supplied with water in a somewhat unusual way:partly groundwater, partly excess rainwater from a green roof that splashes down into the pond. The microscopic examination revealed some striking desmid species. Some of them need further taxonomic investigation.
