New Year, New Project

Sam (and Bailey) and I walked around the property today discussing native species, invasive species, riparian areas, and nut trees. I thought we could start collecting species lists and habitat types to create a sort of "Trees in My Forest" a la Bernd Heinrich. Then we reined it in to start as an iNaturalist project. We can log our observations of species - mostly trees and other woody plants but also birds and mammals and invertebrates and herbaceous plants and fungi and... and... and... this could become a handy tool or an expansive ecological account.

What all can we discover?

Chloridia virescens

Several larva were found feeding on Petunia flowers growing in hanging baskets in my yard. The larva pupated, adult moths emerged, and all turned out to be Chloridia virescens.

Notification from Richmond Parks and Recreation

📢 Heads up #RVA! 📢
.
The main entrance for Larus Park, located off Huguenot Road at Hayden HIll Road, will be affected by two City of Richmond construction projects over the next 18 months. While access into the park via a temporary trail will remain available at this location, parking will not be. The City is requesting that park visitors DO NOT park along either side of Hayden Hill Road to access the Park.

.
There are several other access points for the Park that visitors should plan on using. The closest is along the 3400 block of Stony Point Road. Signs have been placed guiding visitors to the parking. Another is at 3900 Beechmont Road.

.
Thank you for your patience while the City works to upgrade its infrastructure.

An Iranian Bird Guide and Bright Pink Native Plant - Observation of the Week, 1/19/21

Our Observation of the Week is this Bongardia chrysogonum (commonly known as سینه کبکی in Farsi) plant, seen in Iran by @shahrzadasa.

For nearly ten years now, Shahrzad Fattahi has worked as a bird guide, but she got her start in plants many years ago. “Iran is a country that is very rich in plant diversity,” she tells me, 

[and] at first I became interested in plants and I was able to take a short course to get acquainted with plants with taxonomy. Photography of nature was an integral part of my observations, so in the genre of wildlife photography and macrography, I expanded my activities and gradually became interested in birds and butterflies...I work and often travel alone to natural places and photograph the species observed, especially birds, butterflies and plants in different seasons.

It was on one of those trips, in 2016, where she took the photograph you see above.

During one of my trips to Mazandaran province, in a large plain called Lasem, which is full of flowers and butterflies in spring, I came across various plants, one of which was Bongardia chrysogonum

I remember a spring day with natural colorful flowers. A gentle breeze and a butterfly dance, along with the sound of a Common Rosefinch playing across the plains, thrilled me. After watching and photographing the species, I lay down on the grass for a short rest and watched the sky beyond the leaves, which attracted my attention more and I took two photos of it. I did not imagine that one day it could fit in a site like iNaturalist and be introduced to the public.

Shahrzad explains Bongardia chrysogonum grows in many of Iran’s natural areas, and its bright pink color attracts attention (the flowers are yellow when in bloom, however).  It’s commonly known as سینه کبکی, she tells me, which means “breast of the chukar” as it resembles that bird. The plant’s leaves, which are quite beautiful, as well as its tuber, are eaten and used medicinal purposes. A member of the barberry family (Berberidaceae), it ranges from Southeastern Europe into Kazakhstan, as well as North Africa.

After her friend @parham_beyhaghi suggested she share her finds on iNat, Shahrzad (above) signed up in 2017 and has posted over one thousand observations (and added 1,300+ IDs). She has been contacted by several students who are researching plants in the region, asking for information and photos, making her realize “how important this site is in introducing species and helping students and naturalists, and it can be a good communication bridge for exchanging useful information all over the world.

I am very happy to join this site so I can improve my knowledge and connect with other researchers and scientists of nature and use their information to learn. iNaturalist is a source of biodiversity learning in the world and it has made me much more interested than ever before.

Some quotes have been lightly edited for clarity and flow.


- Parham Beyhaghi was the subject of an early Observation of the Week, posted almost exactly four years ago!

- Bongardia chrysogonum has been traditionally used to treat urinary tract infections, and this study shows it may be effective in treating prostate issues in humans.

- It may also be an effective epilepsy medication, according to another study.

Thank you and what's next

I would like to just personally thank everyone who joined and posted observations on this project. Each observation was greatly appreciated and helped us complete our senior thesis. As for next steps this project is going to remain open to allow for postings to still happen which could allow another student to pick up this project next year. This will help in understanding more of where exactly these deer are hanging out and why the population could be so high in these areas. Again thank you to all participants and I hope everyone continues to participate

Larus Park Chestnut Oaks (Quercus Montana)

The upper section of Richmond’s Larus Park is a great reminder that above the fall line of the James, Richmond is still, geologically, at the edge of the Blue Ridge Mountains. Chestnut Oaks don’t tend to live long — not by oak standards, anyway — but while they are living they produce the biggest acorns you will find.

To find this remarkable stand of chestnut oaks, park at the Larus entrance on Huguenot Road, next to the fire station and convenience store/gas station. Walk about 100 yards through some young pines, and you’ll be standing among the oaks.

From "Urban Forest Dweller", August 2020

Hyocreopsis rhododendri

I have spent most of my lockdown time exploring old agricultural fields looking for this BAP fungus. From the reading I have done on this species (unfortunately there is very little research done on this species, so little of it's ecology is known) it only exists in areas with ecological continuity. This means that it normally occurs in areas that have had old coppiced Hazel. It is also believed to be parasitic on the Glue-crust fungus, a fungus that 'glues' the limbs of affected trees together, meaning that potential 'host' trees are easily found.

I have found multiple trees that haven't appeared to have had any sort of coppicing, due to their age and the position of the tree (it was in a hard to reach location). Could this potentially change the ecology of this species? (Probably not, but very little research has been conducted on this species and it's ecology).

I will continue to search for more individuals of this species.

Fun Trick with Search URLS

Do you have a favorite taxon? And you want to be sure to find every observation which might be that taxon?

Or maybe you can think of a taxon people are constantly miss-identifying? (Ugh.)

Introducing your new favorite tricks:
&ident_taxon_id=
and
&without_taxon_id=

How to use them?

Fence

Observed that a fence that runs parallel to Five Mile Rd had fallen into the creek on Township greenspace property. The fence seems to run along the border of State, County, and Township property. Although much of it has fallen into Township greenspace. I'm guessing that the State or County maintains this fence. It looks like there were actually two fences. The initial fence fell into the greenspace long ago and is still there (much of it laying in the bottom of the creek). The second fence built further from the creek, is now also falling into the creek (on greenspace managed land). It would be silly to build a third fence and risk the creek meandering yet again only to destroy a third fence. Suggest that the Township work with County and State to build the fence near the top of the embankment instead of so close to the creek.

Gotta start somewhere 8^}!

Nov. 2108: Took possession of 6.7 acres on site of old Fall Creek School, with vestiges evident around the homesite. A dozen or so mature Garry oaks (Quercus garryana) are on the place, including the iconic one at entrance: 6 ft. DBH, canopy as broad as high, probably pre-settlement age. Outside mowed area around house, ground covered in invasive alien shrub species, particularly Crataegus monogyna and Rubus bifrons; and at least 47 (by eventual count) other introduced graminoids, forbs and woody species. I was astonished to find that despite all the weeds, at least 114 (by eventual count) native plant species are extant, in some cases as single individuals. Fragaria virginiana ssp. platypetala is dominant throughout. Camassia quamash ssp. maximaand C. leichtlinii ssp. suksdorfii are both abundant, as are Brodiaea elegans ssp. hooveri, Potentilla gracilis var. gracilis, Prunella vulgaris ssp. lanceolata and Sidalcea malviflora ssp. virgata. There is a diverse Carex component. And so forth: See project lists.

Not long after I moved in, my near, dear neighbor Tanya Harvey suggested I contact the Restoration Projects Manager for the Middle Fork Willamette Watershed Council, one Audrey Squires. Audrey secured a $11,300 grant to restoring a "legacy oak" site. Starting in July 2019, Audrey's contractor Rosario Franco of Aumsville used a brush masticator on a bobcat, to grind the woody invasives down flat, while his crew sprayed the larger stumps with triclopyr choline, as Vastlan. That left a lot of woody debris in all size classes on the ground, albeit mostly flat and easily traversed. He and his crew returned four more times to broadcast-apply generic clopyralid and clethodim. I paid for one more broadcast application of fluazifop-p-butyl, as Fusilade DX, by Glass Tree Care and Spray Service of Eugene after the grant money ran out. The results of all that treatment is that I don't have an immediate problem with most weeds in the Asteraceae, Fabaceae or Poaceae, and some of the natives in those families appear to have survived. There are still areas dense with weeds not sensitive to clopyralid, however.

In October 2020, I spot-sprayed in the 'oak patch' with either glyphosate or triclopyr, trying to preserve native sedges especially, while not risking the oaks. Six weeks later, I used a belly-grinder to seed about an acre under the oaks; and also the spring-seep in the northern rocky 'bank' between the upper and lower meadows (a spot already rich in showy natives), with a mix of grasses and perennial and annual forbs I bought from Lynda Boyer, "The Prairie Godmother of the Willamette Valley". The mix contains Danthonia californica, which requires 12 weeks of winter stratification to germinate.

Since then, I've spot-sprayed the southern bank with glyphosate or triclopyr, prior to seeding with a mix containing only small-seeded grasses. FWIW, that brings this brief summary up to Jan. 18, 2021. I can't promise frequent updates!

Sasselli e capinere al Parco di Gocciadoro

Da alcune settimane, i birdwatcher segnalavano gruppi di tordi sasselli in diverse zone della provincia.
Qualche giorno fa, il nostro collaboratore, Giuseppe Speranza, durante una passeggiata al Parco di Gocciadoro, ha osservato uno piccolo stormo di almeno 17 individui, in sosta sui grandi alberi del parco.
Nella stessa uscita, avvistate anche almeno quattro capinere, svernante sempre più comune anche alle nostre latitudini!

Dive #458 - Charlaine

On the way back from Clarke Rock, J and I decided to look for hooded nudis before taking Radio Flyer out of the water. Sure enough, they were on the eel grass just off the boat launch. There was also a mollusc of some kind in the background of a photo I'm curious about.

Dive #457 - Clarke Rock

Day dive to Clarke Rock. Wicked surface current to start that cleared up once we got under. Dropped down the chain right to the two GPO buddies who've lived within a few meters of each other for the last few months. Big middens outside of both dens. White-lined tubeworm out on a rock, another GPO. Copper rockfish with a tail fin sticking out of its mouth (would later see it again, being dive-bombed by other Coppers looking for a bite). Normal blood star and a rigid blood star (Henricia aspera). A really white GPO that J found, but interrupted by three Stellers. Finally one wolf eel, with a nice big grin. A mosshead warbonnet in an old scallop shell. Red dorid. Rhino crab. A few green sea urchins with nice hats.

Dive #455 - Elliott Beach

Night dive at Elliott, 27ft max The tide was way out. Beautiful stars out overhead. Lots of spot prawns and dock shrimp, including many shedded casings (zombie army? haha). Opalescent inshore squid to start, padded sculpin, pacific cod, snailfish, two little red octopus, a baby sunflower star, several pregnant red rock crabs, one red rock digging a hole in the sand and using its claw arm like a bulldozer, high cockscomb, and lots of YOY herring in less than 5 ft of water at the end. I took out my reg and switched to my snorkel. They didn't like the exhale.

Середина января и "Серая шейка".

Друзья, с небольшим опозданием (по причине проходившей в эти выходные "Серой шейки") об итогах первой половины января.

Вначале всё-же к "Серой шейке" - Всероссийскому зимнему учёту водоплавающих, который в шестой раз проходит в формате именно всероссийского. В прошлом году был пилотный проект на iNat, который начался сразу после зимних школьных каникул, и проходил 2 недели (10-25 января). В этом году задан аналогичный период (9-24 января), но уже на раннее утро понедельника результаты по количеству наблюдателей и количеству наблюдений более чем в 2 раза превысили прошлогодние за весь период: 130 наблюдателей и 514 наблюдений (63 и 223
в прошлом году соответственно). С количеством видов пока не так прогрессивно - +2 к прошлому году, но и в целом водных и околоводных не так много.

Теперь к самой "Российской зиме": на утро понедельника нам не хватило всего 2 наблюдений до 25.000 (!). Но зато уже 252 вида.

Двигаемся дальше, уже совсем скоро, в последние выходные января, стартует Био-Блиц "10 Зимних выходных", правила его совсем скоро.

Juvenile Newt Mortality & Population Viability

The following information came from this fascinating paper:
Neglected juveniles; a call for integrating all amphibian life stages in assessments of mitigation success (and how to do it), (Silviu O. Petrovan and Benedikt R. Schmidt, Biological Conservation 236 (2019) 252–260))

  • Some juveniles apparently disperse diurnally in contrast to nocturnal dispersal in adults and their emigration has unpredictable timing and direction (they're not familiar with the landscape).
  • Juveniles cross the road in the opposite direction of adults. In other words, when the rainy season starts, juveniles emigrate away from vernal pools to the highlands while the adults are migrating from the highlands toward the vernal pools and reservoir.
  • Post-metamorphic juveniles are extremely small and are therefore more susceptible to dehydration on the road.
  • Juvenile carcasses don't stay on the road long. One study found that 80% of the smaller bodied amphibian carcasses were gone from the road within 24 h. "... the combination of small, soft-bodied amphibians with warm, wet surfaces results in rapid carcass destruction, removal by scavengers or decomposition and thus leaves very little evidence of road mortality events (Santos et al., 2011; Zhang et al., 2018)."
  • Some conservationists have found that amphibian population viability is not particularly sensitive to adult survival and mitigations directed towards post-metamorphic juveniles have stronger effects on population viability than those that improve adult survival.
  • The authors state: "We conclude from the review of amphibian population models that there is substantial evidence that the fate of juveniles is critical and represents in many instances the driving factor for amphibian population dynamics... p 254
  • The Gibbs & Shriver (2005) population model used by HTH takes into account juvenile survival rate. HTH used a hypothetical rate of 0.6 in their 2019 model. But it doesn't look like they're measuring the newts they're studying, so how will they differentiate juveniles from adults to come up with more than a hypothetical survival rate for juveniles?

Old Five Mile Road Embankment - Garbage Cleanup

Decided to focus on the steep embankment on the South side of Old Five Mile Road (the two parcels hi-lighted in green below).

The few feet of berm along Old Five Mile is cleaned up very regularly by dedicated volunteers. It is more difficult to clean the embankment on the South side of Old Five Mile. This is partially because it's fairly steep. It also suffers from very dense tangles of honeysuckle. It's a battle just getting to the garbage in order to pick it up. The picture below shows what is typical. Several bottles inside a tangle of honeysuckle on a steep embankment. It would be much easier to keep this cleaned up if State, County, or Township volunteers could keep the area cleared of honeysuckle. It would also make the greenspace and the gateway into Anderson Township much more inviting.

Some of the items found inside the tangle of honeysuckle suggest just how long its been since anyone made it in to clean things up. This is not to suggest that all vegetation should be removed from the embankment. Black Locust, Eastern Red Cedar, Box Elder, Ash and Sugar Maple trees were all observed growing on the embankment. Keeping control of the honeysuckle would become easier over time if these trees are encouraged to develop into a more mature canopy that helps to shade out future honeysuckle. It'd be easier to clean up the garbage in an open forest as opposed to a jungle of honeysuckle.

"Beet" 1: Baumhasel, 2* Kornellkirsche, 1* vermutlich Prunus cerasifera, aber da fehlt mir noch ein brauchbares Habitus-Foto, daher noch nicht hochgeladen.
"Beet" 2: Blutbuche, 2* Platane, Robinie.
Uferstück: Rosskastanie, 3* Ginkgo (davon mind. 2 weiblich, mit alten Früchten), Gruppe von Metasequoia (nicht Lärchen, wie ich erst dachte).
