Hi there,
as a following of Mabudon/Jay/Purpman's fieldtrip, here is ours! I'll let Olivier Marthaler talk about his trip with Rick over Ontario.
As for the Quebec part, we spent 3 days in the Reserve Faunique des Laurentides, where we visit 3 specific sites: the same one I visited last year with the D. linearis and a all green form of S. purpurea plus 2 others cited in literature that I wanted to check back the presence of D.linearis. For some obscure reasons, as for Mabudon, the precise name of the sites escaped me for the moment
On the first site, we decide to complement what I've observe last year. I saw there Drosera linearis plants growing in several cases in Sphagnum mosses, and several question fused regarding this, and the fact that it could be in appearence a Sphagnum bog but with alkaline pockets allowing this plant to grow properly (surely in association with associated brown mosses as Drepanocladus spp). I'm glad to say that we took several pictures of D. linearis actually growing in Sphagnum mosses, and I took a lot of lectures with my pH-meter this time: the plants is really growing in an acidic media (pH about 4.3). I took a few specimens of the mosses growing with it for further ID.
We also numbered the Sarracenia purpurea's phenotype and checked if we were in the presence of the 'semi-veinless' form as Purpman's defined in last September's CPN. Im the end, I think not. With the help of Olivier 'Hawkeye' Marthaler, we numbered around 2000 plants in 2 differents classes, the 'all-green' form (f. heterophylla), intermediate form (all green with red vein but not any trace of red on the others parts of the leaves) and the typical red form (must have red veins and at least some traces of red on leaves). For proper classification, the judgement was done only on leaves well-exposed to sun. The final count still need to be done, but overall we're about a ratio of 0.33 for each but with a large concentration of the 2 first classes in the first half of the bog.
D. rotundifolia, anglica and linearis were seen growing side by side (in a 6"/15 cm radius) but we aren't sure if we were in the presence of the species (anglica) or the hybrid (x anglica= rotundifolia x linearis). Seed pods were too young to judge if there was any positive seeds development.
On the road back to our camping site, we were fortunate to see a female moose with her 2 younglings (?).
We were unable to find the bog the second day.
On the third day, we find a location that I was unable to find 3 years ago. This site was supposed to host Drosera linearis too but we're not still sure about this. I took a few herbarium specimens for further ID. This time, a lot of D. anglica, still in an acidic bog, but the variations in sundews was quite interesting: rotundifolia, x obovata, anglica and perhaps linearis. We are still unable to confirm the presence or absence of D. x linglica, linearis and x anglica for the moment.
We went on a day walk the next day to see one bog in the Parc de la Pointe-Taillon, but after a walk of 7km in the Parc, we realized that the bog seemed to be in majority covered by Ericacaea, so we turn back home with sores on our feets
After seeing Great Blue whales and Belugas in Les Escoumins, we did a last trip in a canoe to observe beavers in habitat. We were lucky enough to caught it on film and see at the same occasion a few strands of Utricularia vulgaris.
Now back home in my case, I'll try to post some picture and get the data organized soon so I could post a more precise reports soon!
A very special thanks to Olivier for this trip and wonderful personality, I would guide people like this through bogs anytime!
