“…Extant Taxodium flourishes only in poorly drained environments, in regions having mild winters. Rainfall must be year round; Taxodium distichum cannot withstand prolonged summer drought, and requires an annual precipitation of at least 1000 mm (Wistendahl 1958).…”

Five Neogene floras in southern Washington and northwest Oregon indicate that the uplift of the Cascade Range occurred after ϳ8-6 Ma. Miocene floras west of the range (Wilkes and Faraday floras) resemble paleofloras of correlative age to the east (Rattlesnake Hills, Palouse Falls, and lower Ringold). The statistical similarity of Miocene floras east and west of the Cascade Range axis demonstrates that a similar mesic, warm climate across the Pacific Northwest existed during the Middle and Late Miocene. These floras represent mixed hardwood-conifer forests that commonly contained Taxodium (bald cypress) and other mesophytic taxa. Based on Jaccard similarity coefficients calibrated with climatic data from modern plant communities, these paleofloras indicate a climate that was summer-wet, unlike that of the Pacific Northwest today. The annual precipitation was >100 cm, and the estimated mean annual temperatures of the fossil sites were 12-13°C. The Miocene floras indicate that the development of a Cascade rain shadow in eastern Washington did not develop until after the deposition of the lower Ringold Formation in eastern Washington. That conclusion is reinforced by a well-documented climate and sediment sequence in the Snake River Valley, Idaho. There, well-dated pollen sections record a sharp decrease (by ϳ30%-50%) in the annual precipitation regime after the Late Miocene Banbury Basalt and Poison Creek formations and before ϳ3.4 Ma. The existence of extensive late Ringold sediments uplifted on the north side of Saddle Mountain indicates that the structural lifting of the Cascade Range had begun by 3.

“…The likelihood of disturbance and colonization from fluvial action depends in part on the topographic position of a site relative to the channel. Numerous studies conducted in humid temperate regions have identified flow characteristics associated with variation in the distance from the channel bed as the chief control of riparian vegetation patterns (e.g., Wistendahl, 1958;Hosner and Minckler, 1963;Robertson et al, 1978;Yanosky, 1982;Hupp and Osterkamp, 1985).…”

“…Complex gradients combining peat thickness -moisture gradients and pH-calcium gradients were previously found by Jeglum and He (1995). Microtopographic relief, resulting from the erosion and de-position of materials during spring flooding for example, creates a multitude of micro-environmental conditions which lead to a patchy distribution of plant species (Wistendahl 1958;Robertson et al 1978;Hardin and Wistendahl 1983).

With the objective of understanding how vegetation was structured in four Larix laricina (Du Roi) K. Koch dominated wetlands in north-western Quebec, 186 point-centred quarters were sampled in four stands. For each point, both biotic and abiotic variables were collected and species cover was recorded. Divisive hierarchical classification analysis (Twinspan) identified nine vegetation clusters: i) Larix laricina & Spiraea alba, ii) Larix laricina & Kalmia angustifolia, iii) Larix laricina, Picea mariana & Alnus rugosa, iv) Larix laricina & Betula pumila, v) Thuja occidentalis & Trientalis borealis, vi) Abies balsamea & Betula papyrifera, vii) Fraxinus nigra & Onoclea sensibilis, viii) Alnus rugosa, and ix) Eleocharis smallii. Results of the canonical correspondence analyses indicated that the distribution of these clusters was mainly related to (i) distance from shore, (ii) shade (canopy cover), (iii) substrate nitrate concentration (in relation to the abundance of Kalmia angustifolia and Alnus rugosa), (iv) substrate pH (in relation to the abundance of Sphagnum spp.), and (v) substrate conductivity. Several characteristics of the water table also affected species distribution, including pH, depth, and carbon concentration. Further studies should address the effect of the presence of Kalmia angustifolia and Alnus rugosa on larch growth. Résumé : Avec pour objectif de comprendre la distribution de la végétation dans quatre tourbières dominées par Larix laricina (Du Roi) K. Koch au Nord-Ouest de la forêt boréale québécoise, 186 quadrants centrés sur le point ont été échantillonnés à l'intérieur de quatre sites. Pour chacun des points, des variables abiotiques et biotiques ont été récoltées et le recouvrement en espèces a été noté. L'analyse par classification divisive hierarchique (Twinspan) a désigné neuf groupements végétaux: (i) Larix laricina & Spiraea alba, (ii) Larix laricina & Kalmia angustifolia, (iii) Larix laricina, Picea mariana & Alnus rugosa, (iv) Larix laricina & Betula pumila, (v) Thuja occidentalis & Trientalis borealis, (vi) Abies balsamea & Betula papyrifera, (vii) Fraxinus nigra & Onoclea sensibilis, (viii) Alnus rugosa et (ix)Eleocharis smallii. Les analyses canoniques des correspondances ont indiqué que la distribution de ces groupements était principalement reliée à (i) la distance de la rive, (ii) l'interférence lumineuse et certaines caractéristiques du substrat, entre autre (iii) la concentration en nitrate du substrat (notamment en relation avec l'abondance de Kalmia angustifolia et d'Alnus rugosa), (iv) le pH (en relation avec l'abondance de Sphagnum spp.) et (v) la conductivité. Un lien a été démontré entre les caractéristiques de la nappe phréatique et la distribution des espèces, notamment en relation avec le pH, la profondeur et la concentration en carbone. Des études plus approfondies devraient être conduites afin de déterminer l'impact de la présence des espèces Kalmia angustifolia et Alnus rugosa sur la croissance du mélèze.Mots clés : mélèze, tourbière, analyse de végétation, inond...
