Scientific research for the conservation of the species
Activity affecting the species is incidental to the carrying out of the activity
In 2013 and 2014, pollination biology studies will be carried out on American Water-willow (AWW), including breeding system and/or pollinator observation trials in Point Pelee National Park (PPNP). For the plant breeding systems trials, different methods of reproduction will be checked: asexual, automatic and facilitated self-pollination, and cross-pollination. This is done by applying temporary tags to and small bags over, flower buds before opening, and preparing them for the appropriate treatment. Stamens are removed from flowers in the asexual and cross-pollination treatments before pollen is released to ensure only the targeted pollen can reach the stigma. When the stigmas are receptive, pollen will be transferred by removing anthers from the donor flowers and brushing them across the stigmas of the receiving flower; in the case of self-pollination, the anthers will not be removed but will be brushed over top of the stigma(s) of the same flower. When the stigmas are no longer receptive, the bags will be removed, and the flower monitored for fruit set. If fruits are produced, they will be collected and evaluated for seed set. If feasible the seeds will be counted and assessed in the field, and the seeds immediately scattered amongst the PPNP AWW population. If it is not feasible in-field, then the seeds may be collected for counting/assessment in the lab, and will be later returned to the park to be scattered amongst the AWW population. Minimal numbers of flowers will be used; the number of flowers and plants in a population will affect this number. For instance, in a standard non-SAR situation, 6 treatments with 5-10 flowers each would be used at each site. The exact numbers of treatments and flowers will be adjusted based on the number of AWW sites being studied, the numbers of plants in each population, numbers of flowers, etc. Regardless, no more than 10% of the available AWW flowers in the PPNP population will be used for the research. Pollinator observations will occur through the use of visual observations and/or sweep netting of visitors to the flowers. Insects that cannot be identified “on the wing” will be temporarily collected in clear vials for closer observation and/or photographs, and then released. These observations will occur on fair-weather days (at least partial sun, low wind, no rain) when the flowers are open and insects are active. Depending on the activity level of the flower visitors, and the size of the plant population, transects will be accessed by canoe through the population and/or several flowers may be monitored more closely. There may be some temporary impact on plants involved in breeding system trials as flowers will be manipulated in such a fashion that overall fruit and seed set may be reduced as a result of some treatments (e.g. if a plant requires cross-pollination, the flowers involved in self-pollination treatments would not set seed as pollinators will be prevented from visiting).

Location of Activity (province, territory or ocean):
a) all reasonable alternatives to the activity that would reduce the impact on the species have been considered and the best solution has been adopted; Alternatives to carrying out the project focussed on: 1) how to access the population, and 2) whether the seeds could be temporarily removed from the park. 1) The population can be accessed by walking up the east beach or canoeing across the marsh. AWW is located along the shallow eastern edges of Lake Pond and the plants can be accessed using waders or by canoe. Using waders was deemed to be more invasive since it could result in the trampling of roots and breakage of other plant components during the research. The use of a canoe allowed for quicker access to multiple plant locations, as well as a lower impact means of studying the plants (i.e. AWW temporarily and gently displaced to the sides or below the canoe while the research is taking place). There is a chance that some minor damage in the form of plant component breakage could occur from the use of the canoe but it is believed to be less disruptive than wading into the plants to study them. 2) Researchers will attempt to count the seeds from the reproduction studies in situ and then place them back in the marsh beside their parent plants. If this cannot be completed in the field, then researchers can temporarily remove the seeds from the experimental plants and take them to the lab for proper analyses (i.e. counting). If the researchers could not count the seeds adequately in the field and were not allowed to take them back to the lab for analysis, then this would affect the research results needed to manage this PPNP SAR. All seeds will be returned to the park to be placed near their parent plants. b) all feasible measures will be taken to minimize the impact of the activity on the species or its critical habitat or the residences of its individuals; 1) The use of a canoe allows for quicker access to multiple plant locations, as well as a lower impact means of studying the plants (i.e. AWW is temporarily displaced by the canoe). 2) The study allows for ?10% of the population to be affected so as to not jeopardize the AWW’s existence in the park. 3) All study seeds produced will be placed near their parent plants in the park. c) the activity will not jeopardize the survival or recovery of the species. Less than 10% of the population will be affected so as to not jeopardize the SAR’s existence in the park. Since there are ~30,000 AWW plants in the park (as of 2007) and the researcher is restricted to affecting ?10% of the flowering individuals and intends to study far less than 3,000 AWW, then the effects on the overall PPNP population will be low.
