Are there any garden pond experts out there? Does anyone know of a good information source for garden ponds and wildlife?
Earlier I decided it was time I made an effort to remove some of the rotting vegetation on the bottom of my pond. It only has a maximum depth of about 12 inches so I had decided to use my hands to clear small sections every few days. This way I need only disturb the sediment in a small part of the pond at any one time.
Today, with only a few handfuls of mud etc I found 3 hawker larvae and I wonder how many I missed and thus 'killed'.
Is there a best time of the year clear the sediment? If I waited until the colder weather the larva will still be there and, I presume, will be hibernating and inactive so harder to see. Perhaps I should leave the ecosystem well alone as, thanks to the snails, the water is clear .
Thoughts or advice anyone please?
