300 lbs. of Cinnamon


I started writing this dispatch at my good friend Anita’s house. I live in a “low-lying area” (between a creek and a river) that was evacuated so Hurricane Irene could take over the space in a more expansive manner. Anita is a librarian and manager of her branch. Her house–just across town–hasn’t lost electrical power in almost a decade’s worth of big storms. She is the Emergency Contact of My Dreams.
Anita’s wisenheimer (but mainly smart and fabulous) son sent her this email after reading my August 8 post about Rae’s field work with Ursus americanus:
Ma,

I didn't tell you about my plans for this weekend? I'm planning to go swimming with Great White Sharks in the Great Barrier Reef while wearing a wet-suit made out of raw, freshly cut t-bone steaks. I was thinking about poking a wasp nest with my finger and sleeping on a mattress full of bedbugs first, though...

What do you think?

Capture 1
“I was thrilled!”
On Rae’s dad’s birthday, the person whose turn it was to check the traps called Carl, then Carl called Rae to tell her they had a bear. The trap was in a remote area at the top of a mountain all the way up a little winding dirt road. Forest service and fish and wildlife personnel access only.
“It was awesome.”
Cinnamon (not her real name) had taken the bait: cookies with M&Ms from the grocery store. Most black bears are black or a very dark brown. But like people and other colorful animals (flamingoes!), black bears vary in color. Cinnamon is a cinnamon-colored black bear. Her cubs are black. Cinnamon’s real name is the secret agent-sounding Green 99. All bears in the study are named with a color–for the region they occupy–and a number. Except for the first 20 bears at the study’s outset in 2001. Carl and Jon named those bears after their favorite players from the Denver Broncos. (Shoutout to Trevor, Brian, Ed, Rod, and the crew. Raise a paw if you’re with me!)
Cinnamon’s three cute little cubs watched the action from a nearby tree. Unsurprisingly, Cinnamon was through, and was making a lot of noise in the trap. I ask Rae how bears sound. (In children’s stories they speak like humans.) She says they growl and kind of bark.
To recap, we have mama bear in a trap, growling and barking, with her cubs up a tree. “Bears are never very good when you separate them from their babies, “ she tells me. I think, Who is? But I don’t know if I say this to Rae.
This is how it goes once the bear is in the trap:
1)   Stick the tranquilizer gun through the bars at the entrance to the trap, and shoot into the bear’s shoulder area from a close position.
2)   The bear falls over. (The tranq dart knocks the bear out for about two hours.)
3)   Open the door.
4)   Everybody pulls the bear out of the trap. (What must this be like?)
5)   Put/carry the bear to somewhere shady and flat.
6)   Take her/his stats.
7)   If it’s a sow and she has cubs nearby, tranquilize them, if possible, to measure, weigh, and tag them.*
This is a photo of Rae taking Cinnamon’s temp with a rectal thermometer. Cinnamon was at 99.5 degrees; a little low, but healthy. Carl handed Rae the thermometer, “OK, it’s your first time on a bear.” The rectal part was Carl’s version of a surprise.
Rae had her tranquilizer gun moment two days later with Green 68. [Note: Green 68 was lured by pie. Luke, a wildlife biology student intern with the Nevada Department of Wildlife, is tasked with shopping for sweets for the traps. He seems to bring enthusiasm to this part of his job.] Green 68 filled up the entire trap. Rae, a novice, couldn’t miss. The tranq dart is propelled by carbon dioxide, and makes a sound like air moving very fast (ssssshooop). “You know like in the movies the assassins have those guns that place a red dot on the target? It’s just like that,” Rae says. Maybe one day she will have her own nature show where she can choose her wardrobe. (A dream come true, fingers crossed.)
*About the tagging:
1) Carl’s and Jon’s and Rae’s study is out of collars. The collars cost about $5,000 each, and right now they’re in search of money. So, instead…
2) The bears get tattooed. In a monitoring procedure called “mark recapture,” the captured bears are tattooed on the inside of their lip and a tag is affixed to one of their ears. The ear tags “are like insurance,” Rae says. Just pick up a pair of binoculars, read the tag from far away, and record the bear’s location. In the event the tag comes off, the bear still has the tat. This way the bears don’t have to be tranquilized so often for the team to keep track of them.
3) I'm feeling bad about the tattooing. Rae says environmental biologists can’t catch a wild animal and not keep track of it. “The bear is unconscious; you lift up its lip and write,” she says firmly. (I am reminded of when we visited a little farm when she was in kindergarten, and she bottle fed the cutest fuzzy black lamb. I asked the farmer how long she kept the lambs. “Oh, not very long. They become lamb chops,” she laughed. “I love lamb chops,” small Rae exclaimed, holding the bottle to the little lamb’s lips without wavering.)
4) The team keeps track of the number of times their bears are captured. If they capture a lot of bears, and many are first timers, they know there’s a large population.
5) Reminder: the point is to find out where the bears are and what kinds of habitats they’re using in order to, eventually, prevent destructive human-wildlife interaction. (Please see August 8 post.)
Capture 2
Here’s Rae’s recounting of Green 68’s capture:
Green 68 had two cubs that gave us a run for our money. She was in the trap and the cubs were around the trap waiting for her. You have to be really quiet. They’re so little and fast they just zoom by you. There’s such dense vegetation, we couldn’t catch them. We all hid and waited. We tranquilized mom and took her out of the trap to a shady spot on the ground. The cubs came back to their mom in about 30 minutes’ time. Then they started nursing while she was unconscious. They’re about 6 months old. It was easy to shoot them. Carl did it.
Here's Rae and one of Green 68's offspring while it was spaced out. Completely sweet. 
Both mama bears had already been tattooed before their August recapture.
Final shoutout of this post goes to Oba, Rae’s boyfriend in NYC who had their new apartment all ready when she got back, and found the rectal thermometer factoid TMI. This was his maiden voyage as a wildlife ecologist's urban life partner. If he was freaking out, he did it away from his Blackberry.
BTW, the Ray May Fire in NV (mentioned in my last post) was contained in 3-4 days. Hurricane Irene did an excellent job on the Great Dismal Swamp fire, which must be the primary reason she rolled through this part of VA.
Text your mother photos of you with wild animals, remembering to indicate that they’re unconscious and you are not. 

Doughnuts by the fire


Long post.
Last night I received this text from Rae: "Uh oh. Big wildfire and my bear habitat is burning..." My thoughts, in this order, were: 1) Her asthma, triggered by airborne irritants, is just as bad as it was when she was little. She has to take all of her meds. Now.; 2) How far away is the fire and how fast is it approaching?; 3) The gas card I sent has not yet arrived via Priority Mail, so odds are there's not enough gas in the tank to get her as far away as she might need to get; and, finally, 4) Poor bears!
I haven't heard from Rae today, which I believe is a good thing, except she said she'd text when she got the gas card. The Ray May Fire (!) is, at the time of this posting, 70% contained. We've got a gigantic fire raging here in the Great Dismal Swamp, which straddles North Carolina and Virginia. I'm north of the border. We'd had a couple of clear days, but as I write this, the wind is shifting, and I can smell the smoke again, and apparently the smoke is evil. Here are some of Rae's (emailed) comments on the GDS fire:
ahh!! i didn't realize the dismal swamp was PEAT SWAMP!!! Peat is a type of soil that has more carbon than any other kind of soil, plant, anything. When peat swamps burn accidentally or are burned on purpose (to clear for agriculture), more soil carbon is released into the atmosphere than is really imaginable. It's so so so so SO bad and is actually the leading cause of climate change globally. :(
She’s disappointed that no Nevada bears took the bait last week. Look how big the trap is! Carl and Jon and Rae loaded the traps with honey-soaked doughnuts. The bag of doughnuts (or, alternatively, raw meat) hangs from the roof way back in the trap. The bear ambles into the trap and pulls on the bag of food. That triggers the gate at the entrance, which then slides shut. The plan is to trap the black bears long enough to place GPS collars on as many as possible so the ecologists can track their movement. (The bears’ longitude and latitude are downloaded hourly from the collars.) While the bears are tranquilized, the scientists take a DNA sample, too. I would appreciate it if a bear or two would oblige these good people so Rae will learn how to do this stuff. Safely.
The team left some traps in the immediate Lake Tahoe area, which is thick with tourists and summer residents right now. People call the scientists to alert them that a bear has been trapped. I keep trying to envision, say, the Lake Tahoe Welcome Center parking lot with a bear trap in it. (Is that what she’s talking about?) Rae and Carl go out every morning to check the traps set in remote areas in the Eastern Sierra. The parts that aren’t burning.
There are less than 300 black bears in Nevada, all in the Lake Tahoe Basin area, and close to 30,000 living throughout the California wilderness (and, in some cases, dangerously close to people). The Tahoe area has a couple thousand black bears. They roam back and forth, looking for good habitats. The jaguars of Texas and Mexico are supposed to do the same thing, but there’s that highly inconvenient La Migra fence in their way. Jon left Rae and Carl in Nevada last week to work the jaguar problem: how to allow jaguars to move around the border region in their natural pattern without interfering with immigration. Jaguars are one of the few migrating species along the border. If they aren’t able to move around, there’s a good chance they’ll go extinct. 
Shall we lighten up?
In the run-up to the post-trap bear research adventure (fingers crossed for post-trap bear research adventure), there’s always good old US culture world:
1. Rae said Carl and Jon’s road trip to an outfitter–a big store for serious outdoors people–in Reno was like “traveling to Bloomingdale’s” for her. She’s glad she didn’t bring anything cute to wear; “People haven’t heard of fashion.” She’s even been wearing a sweatshirt, which is significant adaptation for a woman who was wearing Louboutins this time last year. I’m hoping for a photo of Rae in the cap Jon and Carl gave her. The cap says, “I Am Bear Aware.” (The fellas rejected her NYC law firm-branded hat. “Can’t have that,” they said.)
2. When Rae was tracking lions in Tanzania with the African Wildlife Foundation and the African People and Wildlife Fund two summers ago she had water buffalo for dinner one night and pasta (left by an Italian researcher) the next. Last week at Carl’s she had meat loaf (she thinks maybe for the first time) made with elk and served with hot sauce. Elk gravy being hard to come by?
3. She tells me she went to water aerobics at the Carson City community pool. We agree that water aerobics is a great workout, and we go together when we can. Rae asks me why the demographic is always people “your age and female.” I posit that young folk peek in at the classes, decide it’s for old women (= scary feeble), and pass, so they never know.
4. “There are zero black people. It’s just me. That gets annoying.” Everybody in Minden knows her whereabouts. “Was that you I saw jogging yesterday…?” But there were lots of black people at the outfitter in Reno. “Even women.”
5. It’s beautiful there. There’s snow on the mountain peaks. She’s happy to be in the wilderness, breathing what was, before the fire, gorgeously clean air. She says the men “are really masculine.” Manly men. Gaston from Beauty and the Beast.
6. On Saturday night Rae really wanted to go out. She tuned in to the one radio station that sometimes plays pop. “I wanted to put on heels, get a drink, and dance.”
Call your mother when you're in the wilderness. Plenty to discuss! [Note: Just got the text. The gas card arrived!]
