This should have 10,000 views! Curious, is there a transcript?

Thank you for this wonderful webinar!

watching from Alaska!!!

A strategy is needed, thru species selections or rate, etc, that will thwart Canada Goldenrod! This plant is responding just like native species to all of our management options? Especially on CRP acres, where we can’t graze.

Awesome video - so interesting!!

One would have to worry about FWS budget if Trump is re-elected? He has that track record.

I saw my 1st burying beetle this morning! (Southern Illinois)

Unfortunately the national zeitgeist assumes fish barriers = bad. Here in the lower Colorado River Basin where most of our habitat is full of exotics, we are adding fish barriers and renovating streams to restore native fisheries. Fish barriers = GOOD here for the most part. It is important for everyone discussing barriers that the automatic "barrier=bad" narrative be qualified as to whether a particular barrier is a negative or positive impact on native fisheries!

Wasn't expecting Dr E to be a speaker, I just chose a random webinar to watch. He's my old plant ecology professor. What pleasant surprise! Good times at Sinking Pond!

Good one. Thanks for the sharing

A few questions and observations: 1. I read that the first brood emerges in April. Is global warming affecting this? It seems that, given how spring nectar appears to be more critical than summer nectar, that a follow-up study should look at only spring (and flowers that bloom at the mid point) flowers. If the Karner, for instance, requires mid-spring and late-spring resources but not early-spring - and also if there is a difference in how much is required in the periods - and, probably most importantly - if the different species that are typical in the successful habitat peak during just one of the periods... The author(s) of a study of flowering meadows in the UK seemed surprised at how much "weeds" contributed to the spring nectar level, arguing that those species are critical for providing needed nectar. Perhaps non-"weed" species could also have contributed but had been extirpated, though. The poor nectar sugar level and nectar production level of R. hirta is something I was aware of prior to seeing the charts you presented. Yarrow is also not a particularly impressive performer. It does appear that the species chosen for the more affordable flowering meadow restoration seed mixes not only lack spring performance, they are often chosen due to the inexpensive nature and pioneer species behavior (e.g. R. hirta and A. millefolium). R. hirta, though, is apparently allelopathic so it may also hinder the establishment of rare preferred species, potentially wasting some species' seeds. My suggestion has been to sort seeds into different submixes and spread them in separate areas (or in strips), so that the less-competitive species have more of a chance against the allelopathic species in particular. The UK study found that the highest nectar producer was Jacobaea vulgaris. I wonder if Karners have historically relied, at all, upon such non-native "weeds" during the spring period, given how prevalent that one has been historically in some areas (including Ohio), due to agriculture. I wonder what butterfly species, if any, might appear to be able to sustain themselves within their traditional habitats but have relied upon agricultural disturbance to truly persist. The Karner, I vaguely understand, doesn't migrate/move much. Therefore, I assume it wouldn't be moving from a nearby agricultural field and back to its normal habitat to fulfill its nectar requirements. 2. Asclepias flowers distribute their pollinia by ejecting them into insects' eyes. I don't know if this has a significant impact on the success of the butterflies or not. Honeybees are blocked from the hive if carrying too many but with butterflies I wonder about vision impairment. One study said Speyeria cybele shows a strong preference for milkweed so perhaps vision impairment isn't a serious issue. One study found that Cynanchum laeve is strong nectar producer. The same study found high nectar production for A. tuberosa. C. laeve may be relevant to the Karner, particularly for those who want to provide habitat for the monarch butterfly and the Karner simultaneously. Having both C. laeve and A. tuberosa on a site seems as if it would be more beneficial, versus just having one. I wonder if the symbiotic ants would feed on the nectar of the C. laeve, too. 3. Why was a species of rose chosen for evaluation? I thought roses don't produce nectar. 4. If more summer-flowering species will be used in a follow-up, I would like to suggest including Cirsium altissimum, Cirsium discolor, Silphium laciniatum, and Helianthus maximiliani (and/or similar). I realize that these species aren't particularly easy, as they can't be grown quickly in greenhouses. However, it would be good to know if they have relevance to a small blue butterfly despite their stature. It would seem ideal to be able to have flowers present that can benefit both small and large butterflies. Also, as the Karner has been shown to have a preference for non-native spotted knapweed, perhaps some native species that could be reintroduced (as some likely were present in the 99.x% of original oak savannah, even if we don't see them now in the remnants) could be identified for their usefulness for butterflies. I have seen a variety of butterflies foraging on thistles, including small ones like skippers. Thistles have been shown (at least some species) to produce substantial nectar. There are also some lower-stature thistle species, although perhaps not in Ohio. It would be good to know if Liatris ligulistylis is used by the Karner, as it appears to be one of the favorite nectar plants for the monarch. Additional species I would evaluate are Dalea purpurea, Echinacea pallida, Amorpha canescens, Solidago caesia, a white-flowered native aster, and a blue-purple native aster. The first three species are commonly used in prairie restorations and are affordable to obtain in seed. Amorpha canescens is also listed as being a frequent component of oak savannahs and it is shrubby. Various asters are also easy to obtain. 5. What is the minimum size a plot of land must be to successfully host a stable population of the Karner? Could, for instance, someone purchase 10 acres in order to recreate an oak savannah and have that be large enough? 6. I read about a project to establish Karners in a former parking lot. That, I assume, had no cover. I have also read that Karners are associated with barren areas, not solely with oak savannahs. Does anyone know why certain areas that lack cover are places the Karner can successfully survive in? Oaks take a long time to grow to maturity, so if there is any possibility that a restoration project can use something like degraded land (e.g. a former parking lot), without having to wait for the oaks to become mature, that would be ideal. 7. Various seed sources claim that they sell the right kind of perennial lupine (L. perennis). Some warn against buying seed from other sources because hybridization with L. polyphyllus can, according to them, produce plants that look like L. perennis but which are lethal to the caterpillars. Has anyone done research to identify a reliable source of lupine seed from a commercial grower/seller? The most ridiculous thing would be to create a Karner habitat and have the lupine be poisonous to them. I also wonder about the timing of nectar release... if that has anything to do with species usefulness for the Karner. Are there any species that would be in their habitat (particularly if it is restoration habitat using commercially available species) that may not have any (or limited) usefulness to them because of the timing of nectar production)? I don't know much about Oenothera biennis but I wonder if a species like that one might not be useful to the Karner. Thank you.

Watching from Guyana

great overview of GIS options in the storymap -type space ..

an animal that doesn't have a backbone: Drumpf.

There are some species of insects that can also reproduce asexually. They do this by a process called parthenogenesis

I didn't even know that the Xerces Blue butterfly went extinct - thanks

Aborific! - is that part of his "What's New Pussycat?" film dialog.

I thought a fungi was the largest living organism on Earth?

"feeling increasingly guilty about these large landscape plans because they were leaving out so much...I know for a fact that the vast majorities of locations of narrow and endemic species and natural communities are totally missing from this...wildlife corridor." Reed Noss

pretty tragic that only the Earth First! Journal would be the popular venue for these conservation land corridor projects. Thanks to Reed Noss for his crucial work.

I am thrilled!!!!!!!!

I agree with the fact that no baseline information is needed to justify conservation actions for bumblebees and other native bees . This makes me more confident that I´m moving on the right direction with my efforts of creating pollinator habitat in central Mexico.

Awesome work! Thank you.

wow, the amount of resources was great to find out because i have begun concerned about our small town of 15000 which is an overwintering site that is usually in the top six sites in CA. I just found out that honey bees hives were allowed with a permit which was just reduced to almost nothing to get becuase people want to save the bees. So on days warm enough for monarchs to look nectar, they would be in direct competition for the scant resources during that oct-feb time frame when the monarchs are here. We are not agricultural or anywhere near a source that the bees could pollinate. so much resistance to this education. thanks for the info

Thank you

watching in Indiana

Great presentation!

You can read a paper (free) on the topic covered by Jim Cane by searching 'Gauging the Effect of Honey Bee Pollen Collection on Native Bee Communities' - it was published in Conservation Letters (2016).

Sounds great! Embedding your video online Planeta.com planeta.com/natural-areas-conference-2018 A couple of questions: Will the event have live and recorded video? What sort of trips are being offered outside of Bloomington?

He is such an important thinker and defender of nature. The father of the theory of wildlife corridors to create a network of preserves.

Apologies all - the beginning of this recording got cut off, but nothing critical to the presentation was lost.

Too much farming in Wisconsin. I went up north recently and I haven't been up there since I was 16. I'm 36 now and I can tell you first hand that it looks nothing like it used to. It looks more like Indiana now and that upset me so much I didn't stay. Tourism has decimated the wilderness and there are extremely few places where you can go that are still relatively wild.
