When we think about planting for pollinators, the first plants we reach for are often ones with obvious flowers, usually bright and showy, perhaps with an attractive scent, and lots of pollen and nectar. Most of these will be insect-pollinated plants, which is why they are so attractive to pollinator insects – they have co-evolved with pollinators to reap the reproductive benefits of insect visitation.
But pollinators also use plenty of other plants that we wouldn’t think of as being ‘pollinator plants’, particularly plants that are pollinated by wind, like conifers and grasses. Some grasses are pollinated by bees. And some bees feed on fungi. These interactions have been observed by scientists and naturalists for centuries, but are often forgotten when we talk about pollinator conservation.
This is one of the key challenges with the ecosystem services concept. Trying to justify conservation of pollinator insects because they provide us with benefits, i.e. fruits and seeds from plants they pollinate, is not always useful. Partly because this approach overlooks the fact that pollinators also need lots of other resources to survive, some of which we may not benefit from. And separating ‘insect-pollinated crops’ (e.g. almonds, stonefruit, berries) from ‘wind-pollinated crops’ (e.g. wheat, rice, corn) when we talk about managing farms for pollinator conservation, ignores the fact that some pollinators will regularly visit wind-pollinated crops to collect pollen for food.
I’m currently writing a review of records of pollinator species visiting plant species that we traditionally assume to be wind-pollinated, after noticing some of these interactions at field sites and in my own garden (stay tuned!). I didn’t find any records of some of these plant-pollinator interactions in my literature review, so I’m recording them here. One-off ecological observations are rarely accepted by academic journals, because they are not considered scientific studies. But, in conjunction with other knowledge, they can provide important information for future research hypotheses.
