the buildings had been removed and five of its six ornamental fountains had been razed from the site, using charges of blasting powder. However, one fountain was left intact on the site where the main building had been located.289 This was variously described by The Star as a “memento” and “memorial” of the exhibition and was said to serve the purpose that Mr Joubert intended to be fulfilled by the foundation stone.290 No information concerning the fountain's removal or relocation VOLUME 2.

The old fe has been strengthened by the addition of two more wires, and has been properly strained a stayed. An iron gate has been put up at the corner of the fence nearest town, and by the er of a stile, the members are enabled to get to the ground.”108

Soon after this meeting and once the new Club's finances had been determined the pavilio the Canterbury Club's former grounds was divided into sections, relocated to its present sit the Oval and reassembled by George Blockley for the sum of £28 and 10 shillings.109

Sheep grazing in Hagley Park, 1910 `In the past, animals grazing on urban green spaces like Hagley Park, Christchurch, would have been a common sight. Farm animals were kept in urban areas well into the 20th century and parks were a convenient place to house and feed them, particularly if saleyards were nearby. Owners had to get permission from the local council – but not all did, particularly in the early days of settlement when local government structures were still emerging.`

The ANZECC (2000) sediment quality guidelines are used in this section to assess the potential effects that sediment quality may have on biological communities inhabiting 10 the stream. Increased concentrations of metals in stream sediments have the potential to adversely affect stream biota that inhabit these sediments.

15 the exposure of organisms to pore water within the sediments. Metals adsorbed to Toxicity arises through sediment particles are in equilibrium with the metals in the pore water. The concentration in the pore water is a function of many factors 11 including the redox state of the sediment (how much oxygen is present) and the rate of diffusion between the pore water and the overlying stream waters. Concentrations can in some situations become high enough to exert toxic effects on biota. It should be noted however, that toxicity may arise from constituents other than metals. Ammoniacal nitrogen is common in stream-bed sediments 19especially if organic matter builds up and the sediments become anaerobic. A number16 of studies have shown that ammoniacal nitrogen in sediments is often implicated as the prime causal agent of toxicity.
