Feasibility study of a template model for assessing gravel pits as passive ecological reserves

Abstract

This study aimed to research the use of a template model for assessing the feasibility of establishing passive ecological reserves within gravel pits that are arguably sites of considerable ecological value due to their pocketed nature. Within Part 1 a preliminary template was developed from the Prebbleton Gravel Pit Concept Development Plan (for a passive ecological reserve). Once an outline was constructed, a further literature review was undertaken and necessary modifications made to the template where necessary.

The template was then applied to five gravel pits each of variable nature however located in a single region in Christchurch (Halswell/Wigram area). Two of the sites are currently subject to in fill, two are still being excavated and another is currently occupied by a go-cart track facility. In applying the template to these variable sites, the intention was to reveal weaknesses within the template and subsequently make modifications to the template where necessary. Due to time and money constraints, several factors for consideration within the template model were reviewed on a broad basis rather than in significant detail for each site. These factors include history of the area, land type as well as cultural history for example.

Several observations were made through application of the template to five different sites as well as a further review of the literature. Modifications could be made to the template model from this research undertaken. Observations included the extensive time and costs involved in a feasibility assessment, the potential for a feasibility checklist to be used as a decision making tool and the need to assess visitor demand potential.

The final conclusion was that the modified template has considerable benefits when assessing the feasibility of passive ecological reserve areas within gravel pits. In suggesting this however, priority for research of the various factors may need to be established in order to effectively allocate time and funding that may be limited for feasibility research.
