Leap Day night smells like lilacs

On my walk home along Shattuck, the air smelled like lilacs, like the east coast lilacs in my community garden plot. Here are some other blossoms from my Leap Day walk.

Weekend headlines February 25, 2008

The local ecologist is no longer updated via Blogger. Also, we could not migrate our skin, so we are working on recreating the old one. On the afternoon NPR news hour I heard that Berkeley along with Oakland and San Francisco are in the top ten greenest cities in the U.S. The number one city is Portland with a 4.8 score for “green living” while Berkeley is number seven with a 2.8 score for “green living.” Recently a friend and I wre struck by the lack of stormwater management in Berkeley. This was foremost on my mind watching the recent downpours run off into the storm drains. Maybe Berkeley can improve its score by installing green streets (see Portland, Oregon) and permeable sidewalks (see San Francisco). Here are other headlines from the weekend. UC removes ropes at Oak Grove protest, erects extra barricade Daily Planet Critics organize against Apple Moth spraying in East Bay Daily Planet Cody’s to move Downtown, leave 4th Street Daily Planet Pelican to trail walkers:

Runnels in Cordoba, Sevilla, and Madrid

Coincidentally I saw the runnels, or channels designed for irrigation in the garden (read here ), at La Mezquita de Cordoba, Spain pictured in Rain Gardens: Managing Water Sustainably in the Garden and Designed Landscape by Nigel Dunnett and Andy Clayden. I travelled in Spain before reading the book which I borrowed from the Berkeley Public Library. Although I did not photograph runnels in Cordoba, I did photograph runnels in Patio de los Naranjos (courtyard of the orange trees) in Sevilla , pictured above and below, and in Parque del Buen Retiro in Madrid. Dunnett and Clayden use the term gully instead of runnel. They write, In the Moorosh garden of the Mezquita, Cordoba (Spain), water is channelled through a series of gullies to each orange tree set within the cobbled patio. Water was a valuable and scarce resource that needed to be used widely. The flow of water can be regulated by inserting timber boards into slot sets within the rills. Parque del Buen Retiro

Tree Walk: Broadleaf tree leaf characteristics

UPDATE: Please visit our new blog site . Read our latest posts: Runnels in Spain and Weekend headlines . As always, we appreciate your readership and comments! ____________________________________________ As flowers bloom blossom and leaves leaf buds unfurl, I am reminded of leaf characters. Several broadleaf tree leaf character diagrams were printed in the Summer 2004 issue of the original local ecology newsletter. The diagrams are included below along with definitions from How to Identify Plants by H.D. Harrington. Simple and compound leaf parts Blade is the "expanded usually flat portion of a leaf or petal." Compound leaf is a leaf "completely separated into 2 or more leaflets." Example: California buckeye. Leaflet is "one of the divisions of a compound leaf." Petiole is the "stalk to a leaf blade or to a compound leaf." Petiolule is the "stalk to a leaflet in a compound leaf." Pinnate is a "compound leaf with the

Weekend headlines February 10, 2008

Last week I missed Ron Sullivan's tree article titled " Trees show their bones and history in winter." In other local trees news, the University of California has initiated Phase I removal of pines affected with pitch canker on the Gill Tract in Albany. The economics of environmental issues were featured in two articles this weekend. An SF Chronicle article titled "Where does convention trash go?" discussed efforts to host more environmentally friendly conventions and meetings . Apollo Alliance's Green Cities, Brown Folks forum last fall featured biodegradable kitchenware from the Green Home Environmental Store. The New York Times featured two sides of the recession's impact on the environment . The Finance Market web site argues that a recession will help the environment (ex: "fewer S.U.V.'s sold") while Treehugger.com noted that a recession would hurt the environment (ex:"politicians may redirect their attention from envi

Bird watch: Berries and buds attract robins and cedar waxwings

In the first post on birds, I wrote about creating bird niches , or planting to provide a variety of food sources for birds groups (frugivores versus insectivores). I mentioned that I do not have a yard so much as a few, small growing spaces. One space is 1' x 21' and the other is 20" x 6'. I grow vegetables and herbs in the latter. The other space is already planted with a quince, rosebush, a crocus shrub, and a small tree bearing small, red fruit. I don't know the name. A neighboring purple leaf plum drapes into the space. Finally, there is a space by the front of the lot (there are six units on the lot), near the trash and recycling that supports an unidentified plant. In addition, the neighbor's honeysuckle (or is it a trumpet creeper?) hangs into the space. It is still sunny. I began writing this post three days ago, on a overcast, dull morning. However, the birds - robins, cedar waxwings, and more - were singing, loudly. After almost fo

Outdoor space for small dwellings

Sunshine and 57 degrees, sitting on the (north-facing) stoop of my small dwelling (not pictured here), drinking tea, listening to bird songs, and typing from "Go Outside" in Little House on a Small Planet by Shay Salomon with photographs by Nigel Valdez. Porches on farmhouses were essential for food processing, entertaining guests during harvest, and summer sleeping. Front porches in neighborhoods used to serve as telephones and TV sets: they announced to neighbors you are available to chat, and livened up the street life for those out on an evening stroll. Porticoes, balconies, terraces, and verandahs were signs of a complete house. Some people credit the arrival of air conditioning with the decline of neighborhood cohesion, especially in the South. Porches on small houses provide extra storage, party, and summer guest space. Some are designed and built to convert easily into four-season space, if necessary, at some point in the future. They filter or block sun, an

Super Tuesday Results

Local Alameda County Measure A lost did not meet the required two-thirds vote in favor to pass (county tax to expand private hospital); there were 174,632 votes against the measure. Oakland's school district Measure G won passed with 60,629 votes. San Francisco's park Measure A passed. The Neighborhood Parks Council web site has great summary and detailed information about the bond. El Cerrito's street repair Measure A won passed as well as Richmond's Measure G to reduce maintain phone and cable service taxes.

Super Tuesday Vote

It is Super Tuesday in California and 23 other states. Vote. Surprisingly, there are much fewer campaign signs than the last election season in California. I am surprised because this election will have national and international impacts, but perhaps the scale of the contest - the nation versus the neighborhood and city - and the significance of the vote has deterred folks from publicly committing to a candidate. Perhaps our lawns and windows, sidewalks, and medians will be covered with signs in the fall. Here are the three signs I noticed along my usual routes.

Tree walk: Utility pruning on Blake Street

Utility pruning is the removal of branches or stems to prevent the loss of service, prevent damage to utility equipment, avoid impairment, and uphold the intended usage of facilities. Only qualified line-clearance tree trimmers or qualified line-clearance trainees should engage in line-clearance work. Arborists' Certification Study Guide , Sharon J. Lilly, 2001. The utility pruning in the photograph occurred on Blake Street, south of Telegraph, in Berkeley. The tree is a topped redwood. Topping is an inappropriate and harmful form of tree pruning. (Arguably, a redwood should not been planted beneath overhead utility wires.) Lilly writes, Severe heading causes branch dieback, decay, and sprout production from the cut ends, resulting in a potentially hazardous situation once the sprouts become large and heavy....If a tree has been topped previously...crown restoration can improve its stricture and appearance. Restoration consists of the selective removal of watersprouts, all
