Mt. Rainier Wildflowers 8/31/17

Mt. Rainier National Park reports

Currently BloomingAugust 31, 2017

Pearly everlasting (Anaphalis margaritacea) earns its name. It begins blooming mid-summer and continues blooming well into the fall, outlasting all other wildflowers. Pearly everlasting flowers are not technically “pearly” however. The name comes from white bracts, or modified leaves, that protect the true flower, which is yellow. Pearly everlasting can be found blooming throughout the park.
Find a trail to explore Mount Rainier’s meadows. Bear sightings become more common in late summer/fall – remember to stay safe and give bears plenty of room!

Wildflower Reports

  • Paradise (8/28): cascade aster, american bistort, lewis monkeyflower, pearly everlasting, rosy spirea, arrowleaf groundsel, broadleaf arnica, grey’s lovage, paintbrush, mountian bog gentian, fireweed, false hellebore, huckleberries! Good wildflower trails: Alta Vista, Deadhorse Creek, Myrtle Falls, Avalanche Lily, and Nisqually Vista

Please Note: As snow melts away, it may be tempting to skirt remaining patches of snow that are covering trails. However, by going off trail you are walking on and damaging the wildflowers that you may be coming to see! It is better to stay on trail even if that means crossing snow, particularly in the high-visitation meadows around Paradise and Sunrise.

Rare Manzanita Talk 9/7/17

submitted by Yerba Buena chapter of the California Native Plant Society

Restoring Habitat for San Francisco’s Rare Endemic Manzanitas

SEPTEMBER  7, THURSDAY, 7:30 PM Speaker:  Michael Chassé

San Francisco hosts two of the rarest manzanitas in the world: Raven’s Manzanita (Arctostaphylos montana subsp. ravenii) and Franciscan Manzanita (Arctostaphylos franciscana). These endangered species grew together in a distinct maritime chaparral habitat that once covered the serpentine hilltops of San Francisco. Their story is one of loss, salvage, rediscovery, and serendipity. Michael Chassé will share the story of how San Francisco’s rare endemic manzanitas were brought back from the brink of extinction and how current efforts are returning these species to the San Francisco landscape.

Michael Chassé is a vegetation ecologist for the National Park Service at the Golden Gate National Recreation Area, where he has coordinated natural areas stewardship and rare plant monitoring for close to 20 years. He is a graduate of San Francisco State University’s Department of Geography. His master’s thesis focused on San Francisco’s rare endemic manzanitas.

Everyone is welcome to attend membership meetings in the Recreation Room of the San Francisco County Fair Building (SFCFB) at 9th Avenue and Lincoln Way in Golden Gate Park. The #71 and #44 buses stop at the building.  The N-Judah, #6, #43, and #66 lines stop within 2 blocks.

Why Leaves Change Color? 

California Fall Color

Leaves on deciduous trees change color in autumn from green to various hues of lime, yellow, gold, orange, red and brown because of a combination of shorter days and colder temperatures.

Throughout spring and summer, green chlorophyll (which allows trees to absorb sunlight and produce nutrients) is made and replaced constantly. However, as days grow shorter, “cells near the juncture of the leaf and stem divide rapidly but do not expand,” reports Accuweather.com, “This action of the cells form a layer called the abscission layer. The abscission layer then blocks the transportation of materials from the leaf to the branch and from the roots to the leaves. As Chlorophyll is blocked from the leaves, it disappears completely from them.”

That’s when vivid yellow xanthophylls, orange carotenoids and red and purple anthocyanins emerge.

Really Big Asteroid To Pass Earth Sept. 1

EarthSky reports

It’s several miles in diameter, biggest near-Earth object to pass so close in a century.

Asteroid 3122 Florence will safely pass by our planet on September 1, 2017 at over 18 times the Earth-moon distance. The asteroid will not be visible to the unaided eye. It will, however, become visible in small amateur telescopes by late August, in the course of what will become the closest encounter to Earth by this asteroid since 1890.

Understanding Monarch Butterfly Populations & How To Save Them

ScienceDaily reports

New research provides an explanation for why citizen scientists taking censuses of monarch butterfly populations didn’t note the same drops in population recorded in Mexico, where the monarchs spend their winters. The research supports previous studies suggesting that an increase in available milkweed could help the monarch population rebound.

TO ANYONE WHO believes environmental regulation is poison for profits, California must be infuriating. The state’s pollution policies rarely wilt its perennially blooming economy. For the past nine years, a Golden State-centric think tank Next 10 has been releasing its California Green Innovation Index. The results this year show a continuing trend: For two and a half decades, California’s GDP and population have continued to rise, while per capita carbon dioxide emissions have stayed flat.

Why Wildlife Corridors Are Important

The NY Times has a story “Stitching Together Forests Can Help Save Species, Study Finds” that documents the importance of not isolating species and creating wild life corridors.

a grim rule of thumb among biologists: When a species becomes isolated in a small disconnected patch of habitat, unable to breed with larger populations elsewhere, it runs a much higher risk of going extinct locally. And since many of the world’s forests are increasingly fragmented, carved up by roads and farms, it seems inevitable that many species within those remaining patches will soon vanish forever.

Asheville NC Fall Foliage Color 2017 ‘s Blue Ridge Parkway & Mountains Fall Foliage Forecast 2017 

Forecast: The number one question is: “When is the peak color?” No matter when you plan an autumn visit, in October or early November, you can take a short drive along the Blue Ridge Parkway or other mountain roads to find the best fall leaves color. Elevation and weather are the biggest factors in the color show. Leaves begin their color change at the highest peaks and gradually work down to the lowest elevations. An early frost speeds up the show and warm weather prolongs it.

Nevada National Monuments Targeted by Oil and Gas Speculators

Center for Biological Diversity News Release

Analysis: Nevada National Monuments Targeted by Oil and Gas Speculators

LAS VEGAS— Oil and gas speculators have aggressively targeted two Nevada national monuments under threat of elimination by President Trump, an analysis released today by the Center for Biological Diversity reveals.

Federal documents show that speculators blanketed Gold Butte and Basin and Range national monuments with requests to have nearly 640,000 acres offered for oil and gas leasing — and hard-rock mining claims — in the years before they were designated by President Obama.

“Oil industry speculators can’t wait to get their dirty hands on these incredible national treasures,” said Patrick Donnelly, the Center’s Nevada state director. “To even consider removing protections from Gold Butte and Basin and Range to appease oil companies is the epitome of short-sighted, corrupt public policy. Trump is trying to auction off public lands like they’re part of his crumbling real estate empire, without any regard for these amazing cultural and natural resources.”

Solar Eclipses Offer Great Opportunity For Scientific Discovery

The Guardian reports on the opportunities a solar eclipse offers for scientific discovery for scientists and citizen scientists

it is a phenomenon that scientists have learned to exploit over the centuries, having made numerous major breakthroughs – from the discovery of helium to confirmation of Einstein’s general theory of relativity – during eclipses. Crucially, astronomers are hoping to maintain this success rate on Monday.

scientists believe the eclipse will give them a chance to make major improvements in understanding the solar wind and how it affects Earth. However, there are other effects closer to home that will also be studied – and not just those that concern humans. Over the centuries volumes of evidence have been amassed about animal reactions to the sudden darkening of the daytime sky as an eclipse takes place: birds being silenced, squirrels freezing in mid-stride and bats and other nocturnal creatures making appearances as the darkness increases.

“A total eclipse is purely a celestial event but it can have profound impacts on wildlife on Earth,” said Elise Ricard, of the California Academy of Sciences, in San Francisco. “We want to record those events.”

Ricard and her colleagues have developed an app called iNaturalist which allows users to join the Life Responds project. Volunteers are being asked to record animal activity before and during the eclipse. Other apps will allow them to video those activities.

Annual Yosemite National Park Butterfly Count

Yosemite National Park reports on the Annual Yosemite National Park Butterfly Count

Yosemite National Park initiated its seventh annual butterfly count in the Tuolumne Meadows area in summer 2017. Yosemite coordinates this event in association with the North American Butterfly Association (NABA), an organization that conducts long-term monitoring of butterfly populations all over North America. The purpose of the NABA counts is to determine how many species and individual butterflies can be observed within a 15-mile diameter circle, during a 24-hour period, within the same date-span year after year. Participants spend the day gathering data toward long-term monitoring; raising public awareness toward butterfly conservation; and socializing and having fun with other butterfly devotees.

Mt. Rainier Wildflowers 8/17/17

Mt. Rainier National Park reports

Currently BloomingAugust 17, 2017

Most subalpine meadows are past peak bloom, however that does not mean there are no wildflowers! Many later-season wildflowers like pearly everlasting, rosy spirea, and arrowleaf groundsel are still blooming well. While there are many yellow wildflowers in the park, arrowleaf groundsel (Senecio triangularis) is one of the easiest to identify for its toothed arrow-shaped leaves. It’s also tall for a wildflower, reaching up to 5 feet, and often found growing in large patches along water sources.


Find a trail to explore Mount Rainier’s meadows!

Sand to Snow National Monument Is Safe

The LA Times reports

Trump administration will keep hands off California’s Sand to Snow National Monument

At least one expanse of protected land in California is now officially safe from the Trump administration’s plan to eliminate or shrink some country’s national monuments.

Interior Secretary Ryan Zinke announced today that the administration has no interest in carving up the Sand to Snow National Monument east of Los Angeles. The 154,000-acre monument that includes some 30 miles of the Pacific Crest Trail was created just last year by President Obama. It is the first California monument Zinke has promised to leave alone in the review Trump ordered of monuments created since 1996 that are more than 100,000 acres.

As with such promises Zinke has made regarding select monuments in other states, there seemed to be little rationale to the timing of the announcement, or why Zinke has chosen to publicly comment on this particular property but none of the five other monuments in California, which include Berryessa Snow Mountain, Carrizo Plain, Giant Sequoia, Mojave Trails and San Gabriel Mountains.
