본격적인 11월의 여름으로 접어 들면서 빗물(Waterstorm) 저수지에 자라는 수련이 드디어 꽃들을 활짝 피기 시작.

WATER LILIES

 

Stormwater refers to the runoff of water generated by rainfall or melting snow. It is a major concern for New Zealanders because of its potential effects on the ecological health of our streams and coastal waters, as these systems are predominantly all connected. With the current trend of increasing urbanisation, inflows into our stormwater systems are highly built-up with sediments and nutrients which are turbo-charging the growth of pest weeds and collapsing waterways.

 

NZWR too often sees gross wastes of tax-payer dollars having to be spent on the damage caused directly by pest weeds. Grass carp should be the preferred option, and are generally contained by way of outlet screens. Other aquatic weed control methods such as the use of herbicides and mechanical removal of nuisance weeds result in considerable loss of aquatic life and result in degradation of the habitat through rotting vegetation and sediments that end up in the ocean!

 

 

Located in the township of Orewa is a large stormwater pond approximately 1.2 hectares in size that surrounds a number of residences. It acts as both a feature and stormwater waterway that is home to many native and exotic fish and bird wildlife. In 2016, grass carp were released due to the domination of the pest weed Egeria densa, and like many other sites was threatening to both the wildlife as a health risk, and interfering with the purpose of the site (being flooding control).

 

Auckland Council and NZWR, alongside Hon. Mark Mitchell (MP for Rodney) agreed that grass carp would be the most appropriate, and effective method. Other aquatic weed control methods are more costly, and the likes of herbicides and the mechanical removal of weeds results in considerable loss of aquatic life and can result in degradation of the habitat through rotting vegetation and disturbance of sediments; making it unsafe for humans or wildlife to consume safely…
