“…colensoi., Cladhymenia oblongifolia, X. chondrophylla and Sargassum sinclairii were found in both the shallow mixed weed and kelp forest zones. The absence of these and other large algal species from the algal turf and paint zone is evidently due to the grazing activities of Eoechinus chloroticus (Choat and Schiel, 1982;Grace, 1983).…”

“…The subtidal algal zonation at Rangiwhakaea Bay is typical of algal zonation in moderate to exposed sites elsewhere in the North Island (Ayling, 1978;Choat and Schiel, 1982;Grace, 1983). The consistency of zonation patterns over large distances and a large range of wave exposure has led to several classification attempts.…”

“…The "mixed fucoid and laminarian stands ... at 3-6 m" of Choat and Schiel (1982) were represented only by localised patches of the laminarian Lessonia variegata. This sub-zone was observed to be better developed in sites with steep-sided boulders and high relief (providing an algal refuge from the grazing of Evechinus), and in more sheltered sites (e.g.…”

During a nine-day visit, we investigated the algal ecology of Rangiwhakaea Bay, Great Barrier Island, northeastern New Zealand. Four subtidal algal zones were recognised, and these were mapped along with gravel and sand areas. The four algal zones were dominated by Carpophyllum angustijolium, coralline turf and paint, Ecklonia radiata, and Hummbrella hydra respectively. Carpophyllum angustijolium extended up into the low intertidal, its vertical width varying with the degree of wave exposure. Five other intertidal algal zones were observed. They were dominated by Xiphophora chondrophylla, Splachnidium rugosum and Catenellopsis oligarthra, Pachymenia lusoria, Hormosira banksii, and Cigartina alveata. Sixty-six species of algae were recorded from the region.

ABSTRACT1. At present, marine reserves do not represent the full range of community types throughout New Zealand.2. To assist with the placement of a marine reserve along the Abel Tasman National Park coast (northern South Island), dominant subtidal laminarian and fucoid algae, echinoids and herbivorous molluscs were quantitatively investigated. Results from 100 quadrats collected from 19 random transects at six selected sites showed that algae and grazer assemblages varied between granite and limestone substrata.3. Granite had a high percentage cover of crustose coralline algae (mean 82%-9O%), a sublittoral fringe of brown macroalgae and no Ecklonia radiata or red foliose algae. Limestone sites were distinguished by a relatively low percentage cover of coralline algae (mean 13%) and high cover of foliose red algae and E. radiata (2%-36% cover and 0.2-13.9 stipes m-2, respectively).4. On limestone, molluscs Turbo smaragdus and Cookia sulcata, and the echinoid Evechinus chloroticus were larger than those on granite. On limestone sites with little macroalgae, herbivore size was intermediate. Grazers were more abundant on granite than limestone (mean 34.6 m-2, and 10.8 m-2 respectively).5. Differences in herbivore composition were recorded between granite substrata, while both algal and herbivore composition varied between limestone sites. 6. We suggest that a variety of environmental factors including substratum influence algal and herbivore assemblages along the Abel Tasman coast. 7.It is recommended that selection of a marine reserve site or sites along the coast of Abel Tasman National Park recognizes differences in community structure both between and within limestone and granite substrata.

ABSTRACT1. Four macroalgal, four macroinvertebrate and eight fish species were surveyed at eight sites (three inside, five outside the proposed reserve) over three years before the establishment of the Taputeranga Marine Reserve (MR) on Cook Strait (Wellington, New Zealand). This baseline data set was used to estimate temporal and spatial variability in size and abundance of these taxa, and will be used to quantify taxon-specific changes in size and abundance once the MR is established.2. Statistically significant differences in size and/or abundance were observed for many taxa among the sites. These differences are consistent with the existence of a natural environmental gradient from the west (entrance to Cook Strait) to the east (Wellington Harbour). This gradient highlights the importance of conducting a prereserve baseline survey at multiple sites and over multiple years to better understand the conservation or fisheries benefits that MRs are expected to deliver.3. Two macroalgal, one macroinvertebrate, and six fish species showed statistically significant seasonal variation in abundance. Subsequent multi-taxa monitoring needs to include a seasonal component to capture this natural variability.4. This multi-site and multi-year data set represents one of the most comprehensive and robust baseline data sets available anywhere in the world. It will be used to quantify the ecological changes associated with a newly established full no-take marine reserve. Ongoing monitoring will enhance understanding of the sizes and abundances of key taxa, allow a detailed determination of the conservation effects of reserve establishment, and inform management decisions for Wellington's south coast.
