To determine the actual number of plugs that could be obtained from a sample of plants, we dug 11 plants from the row nearest the estuary in May 1981 (Fig. 50). One of the largest plants yielded 50 plugs (Figs. 51, 52, 53), but the average number of plugs per plant dug was 20, which agreed well with what we predicted based on the average cover.

One of the largest plants yielded 50 plugs (Figs. 51, 52, 53), but the average number of plugs per plant dug was 20, which agreed well with what we predicted based on the average cover. Since the nursery area contains about 300 plants, we can predict that it could have yielded a minimum of 6,00 0 plug type transplants in May 1981. It seems reasonable to assume that cover will increase from 50 to 10 0% by our next major planting effort in May 1982. This assumption translates into a conservative estimate of about 10,000 plug type transplants or enough to plant ha on a m spacing. The Halimione nursery area at lie Grande was established in May 1980 and added to in May 1981 . It contains about 200 plants that can be dug and separated into transplants (Fig. 54). In May 1981 we dug a sample of seven plants to determine the average number of sprig type Halimione transplants that could be obtained per plant dug. We obtained an average of five sprigs from each plant dug (Fig. 55). Based on 20 0 plants in the nursery area, we estimate that there were about 1,000 Halimione transplants available in May 1981. We estimate that the increase in cover by May 1982 will result in about 1,500 to 2,000 Halimione sprigs available for digging at that time which would plant about ha on a m FIGURE 50.
