Plant Macrofossil Analysis

The forest history around Marion Lake in southwestern British Columbia is reconstructed using plant macrofossil analysis. A comparison with a previous reconstruction based on pollen and spore analysis reveals a good correspondence between pollen and macrofossil zones. Significant improvements in the reconstruction of forest history are possible by combining the study of pollen and macrofossils. Thuja plicata macrofossils do not appear at Marion Lake until 6000 BP, contradicting previous suggestions of red cedar presence as early as 10 000 BP. Although not common at present, Taxus brevifolia may have been an important component of the forest prior to the arrival of Thuja. Fluvial input of macrofossils is important at Marion Lake. Charcoal also appears to enter the lake primarily during periods of high runoff and erosion in the watershed, suggesting the need for caution in the interpretation of charcoal data from stream-fed lakes. Increases in total influx coincide with evidence for increased precipitation after 7000 BP. Marked reductions in macrofossil influx coincide with periods of peat deposition upstream from the present lake. Relative percentages of conifer needles are unaffected by changes in influx.

Plant Macrofossil Analysis

We used the techniques of plant macrofossil analysis and radiocarbon dating to determine the minimum residence time of the endangered thread-leaved sundew (Drosera filiformis Raf.) in three bogs of southern Nova Scotia. The minimum residence times are 4240 cal. year BP for Swain's Road Bog, 2050 cal. year BP for Villagedale Bog, and very recent (modern radiocarbon age) for Port La Tour Bog, indicating that the species has likely been in the region for the past 4240 years. Analysis of nearby Old School Road Bog, which lacks D. filiformis today, failed to find any evidence that it formerly occurred there, suggesting that it may not have been more widespread in the past than it is today.Key words: Drosera filiformis, thread-leaved sundew, plant macrofossil analysis, radiocarbon dating, bogs, minimum residence time.
