Tongariro National Park: Dr. Marshall, in moving the adoption of his report as representative of the Society on the Tongariro National Park Board, stated in reply to a question that it was difficult to estimate just what area of the Park was covered by heather as it was so scattered. The heather did not grow on bare ground but chiefly where the native vegetation had previously been burnt off. The heather had been planted, without the authority of the Board, by the then warden of the Park, with the intention of liberating grouse for sporting purposes. Dr. Archey suggested that the possibility of eradicating the heather by mechanical means such as bull-dozers might be explored. The report was adopted. Tongariro National Park Board. Report of Representative. I visited the Tongariro National Park on 27th January, 1944, in company with Mr. Lawrey, acting secretary of the Board, and Mr. Boulton, field inspector of the Lands and Survey Department. The area on which heather (Calluna vulgaris) has been growing in the Park for about 20 years is considerable. Its extent, however, is not definitely known; it is not exactly certain where it was originally sown by the late Mr. Cullen. Consequently the question as to the rate the plant spreads in this area cannot be definitely answered. At the present time it is growing most thickly at the point where the road to the Chateau leaves the Main Highway. In this locality it is growing on both sides of each of the roads. It does not extend far from the road on the north side of the Main Highway, but on the south side, it has an irregular border extending at times to a distance of one mile from the road. On the sides of the road to the Chateau it grows thickly as far as the tongue of bush through which the road passes, but was not seen on the south side of that point. Although mainly marginal to the road it does not grow on the bare soil exposed on the roadside. Near the Chateau road the heather on the sides of the Main Highway is almost continuous for some distance back from the highway, but it gradually decreases in width until it becomes purely marginal and patchy, and was not seen after passing 15 miles eastward from the Junction. It was the practice of Mr Cullen, as stated to the writer, to burn off the native vegetation and sow the heather seed on the burnt surface for the sd did not strike when scattered amongst the growing native vegetation. It is not possible to say now where the native vegetation was burnt, but remains of burnt scrub can be seen in many places where the heather is now growing. No heather plants can be seen on the bare ground exposed four years ago when the road to the Chateau was re-aligned. It is probable that Mr. Cullen sowed the heather seed by the roadside. He had a consignment of 40lb of heather seed. Close inspection of the vegetation opposite Roderick Gray's whare, a locality which has been undisturbebd for many years and where the ground is wet, shows that the heather has old, straggly stems 3 feet high. The ground is carpeted with a thick growth of native plants—Coprosma, Dracqphyllum, Lycopodium, Gleichcnia, Pimelia—close growing small plants. Very little young heather could be seen amongst the native plants. On dier ground the heather grows as rounded bushes about 2 feet high and 2 ½ feet in diameter. These seem to remain separated. The plants do not grow close together nor could young plants be seen between them. In some places, however, where there was some native vegetation mixed with heather, there were numerous young plants. If heather seed is distributed by wind its spread must be very slow.
