Must Read: Human impact on NZ birds measured in millions of years

6/24/2021

0 Comments

 
Picture
Despite innovative conservation efforts in the country over the last 50 years, over 30% of extant species remain threatened with extinction, and nearly two thirds could be under threat in the future.

According to the authors, if New Zealand’s currently threatened birds go extinct, the macroevolutionary impact could be 10 million years. That means up to 10 million years will be needed to return to today’s biodiversity levels by natural evolutionary processes. It would take 4 million years to recover the diversity lost in the less than 250 years since Europeans arrived.

Sediment: 1.32 million cubic metres a year in the Kawarau arm!

6/24/2021

Picture
The 2012 Clutha catchment sediment management plan estimated that 1.32 million cubic metres of sediment is deposited in the Kawarau arm each year! This is the same volume of concrete in the Clyde Dam!

Pre-dam, an estimated 2.6 metric tonnes passed through Balclutha every year with 60% from the Shotover river. The Clyde dam now traps 93% of this, with much of it settling between Bannockburn and Cromwell.

Weed Harvesting: How effective has it been in Rotorua Te Arawa Lakes?

6/21/2021

0 Comments

 
Picture
Last week we met the managing director of Lakeweed Harvesters & Contractors to access if we could benefit from a weed harvester on Lake Dunstan. There was a lot of positives to investing in this machinery but also some concerns.

We are currently in talks with LINZ, Contact Energy and the council to access the risk of spreading Lagarosiphon downstream of the dam. Lagarosiphon management costs NZ millions every year and we don't want to increase this cost. Lagarosiphon is already between the Clyde and Roxburgh Dam but currently not lower downstream.

The company we met with currently work on the Rotorua Te Arawa Lakes and a 2020 report accesses the effectiveness of weed harvesting to control aquatic weeds. To read the article and summary, click 'Read more'.

Must Read: 1987 Report into the Recreation Potential for Lake Dunstan

Read Paper
What was predicted for Lake Dunstan?

In 1986/87, Dr Reiner Jaakson, a Professor of recreation, geography and tourism from the University of Toronto visited Cromwell. He was commissioned by the Ministry of Works and Development to access the opportunities Lake Dunstan had for the local community once created.

Dr Jaakson described the potential use of the lake, priorities and market potential to town could benefit from.  He concluded Cromwell had a positive future for tourism and that we should not compete with Queenstown, but offer a different, more relaxed experience for the domestic market.

The paper summarises what activities the town should focused on, at which locations around the lake and what facilities should be built.

Lake Dunstan is the 26th largest lake in NZ at 26km2. That's nearly 24 times smaller than the largest, Lake Taupo!

It is also the 3rd largest artificial lake after Lake Benmore & Aviemore. There are over 60 man-made lakes in NZ created for power generation and water supply.

Curious about Lake Dunstan's water quality? Check out LAWA

Land Air and Water Aotearoa (LAWA) uses the Trophic Level Index (TLI) to monitor water quality in New Zealand. This measures four parameters: water clarity, chlorophyll content, total phosphorus and total nitrogen creating a final score. Over the last 10 years water in Lake Dunstan has scored between 2.1 and 2.8. These scores fall between ‘good’ and ‘fair’ [1,2].
‘Good’ is classified as oligotrophic lake conditions. Oligotrophic lakes are found to have high oxygen content and low organic content meaning algae and other organisms are rare. ‘Fair’ is where the lake is mesotrophic, meaning water is average due to moderate levels of nutrients and algae
