Horseshoe Lake Reserve, Trip #44

cc scenery IMG_1847

Horseshoe Lake is a former meander of the Avon River, which eventually became cut off. Following the earthquakes, it has become generally wetter.

cc waterway IMG_1848

Water covered with azolla and duckweed, lined with rushes, sedges and toetoe.

cc people IMG_1808

Searching the water.

We visited this site in July (2017). Below is some of what we saw.

Animals

cc catepillar IMG_1855

A catepillar, probably of a moth or butterfly (Order Lepidoptera).

cc cricket IMG_1880

Ground cricket (Subfamily Nemobiinae).

We used a microscope (20-40 x magnification) to look at some of the water. There were lots of creatures, though most were still very small, and most were very active. The two photographed below are both tiny crustaceans.

cc Daphnia IMG_1859

Clam shrimp (Order Diplostraca).

cc ostracod IMG_1902

Ostracod.

Plants

The surface of the water was virtually covered with azolla and duckweed.

Azolla is a fern that contains a cyanobacteria, which converts atmospheric nitrogen into a form the azolla can use. In return, the azolla provides the cyanobacteria with carbohydrates.

cc Azolla rubra IMG_1819

Azolla rubra.

cc Azolla rubra and Lemna minor IMG_1812

Azolla rubra and duckweed (Lemna minor).

cc Myriophyllum triphyllum IMG_1869

Water milfoil (Myriophyllum triphyllum).

Rushes have a type of tissue within their stems called aerenchyma. It has large gaps, that allow gas diffusion to occur within the plants, thereby enabling the movement of oxygen and carbon dioxide (which are required for respiration and photosynthesis).

Great soft-rush (Juncus pallidus).

cc Carex secta IMG_1841

Pukio (Carex secta).

cc Cortaderia richardii IMG_1833

Harakeke (Phormium tenax).

cc Cordyline australis IMG_1842

Cabbage tree (Cordyline australis).
