Given the high rainfall in the Otways, many creeks ripple through the gullies, sometimes carving their way through the porous sandstone, forming dramatic waterfalls that fill the air with their soft moist. Numerous small mosses and ferns cling to the dank stonewalls, providing excellent hiding places for tiny tree frogs and other amphibians and insects. Despite their tiny size, the frogs call out to their mates with an amazing volume, sometimes even managing to drown the sound of the waterfalls.
The cinnamon-brown, wiry pelt of the soft tree fern provides a perfect home for another, tiny fern species.
Another prehistoric plant in the Otways is the tree fern, of which two species, the soft tree fern (Dicksonia antarctica), and the rough tree fern (Cyanthea australis) are the two most common. Once food of the dinosaurs, this beautiful, almost regal plant became highest horticultural fashion during the Victorian fern craze, from the mid 1800s to the early 1900s, and has been newly popular since the 1990s. The two species can easily be recognized by their trunks; the soft tree ferns is like wiry pelt of a mammoth, whereas the rough tree ferns is more like a scaly reptile. Tree ferns are quite hardy, up to -10 degrees C/ 10 degrees F. They grow slowly, about 30cm/ 1 feet every ten years, so large specimens are expensive to buy, but at the same time, they make an architectural statement even in the smallest of gardens with their gracefully arching, lush green fronds.

During the past year, several Finnish organizations with potential capacity for owning and managing Sipsalo have been contacted. The local universities, the National Board of Antiquities and the Finnish Cultural Heritage Foundation have been some of the suitable candidates. The tough economic times have certainly played in as great interest have been shown by many, but so far, none of them has had the courage and money (a long time commitment like this demands a great deal of planning and resources) to buy Sipsalo, and secure its future for the coming generations. Understandable, but at the same time, very sad and disappointing.

For a while, I almost lost my hope for Sipsalo, and felt that maybe nothing will came out of all work that I and many others have done to rescue Sipsalo (for example, an article that I wrote about the international interest for Sipsalo was published in Turun Sanomat in June 2010 - all response was very positive, but there were no other immediate results). Then, last week I was told that Katri Sarlund from the city council of Turku had made an initiative that the city should purchase Sipsalo.
After contacting Katri, we agreed on that an international petition by the community of researchers, scientists and writers would be highly desirable, and probably effective in promoting the cause. So I wrote one, and so far, I've been very happy to receive great response from everyone I've contacted. In January, Turku City Council will receive an international petition letter for Sipsalo with a handsome list of supporters from three continents.
So no happy ending yet, but I do have high hopes for one. And even if the work in not quite done, I already admit that I have learned a lot during the process. Like that next time I try to save an old garden, I will go and take a lesson in community organizing first. Nevertheless, I am very glad that I've tried and I sincerely hope that Sipsalo at last will be saved to the coming generations. I will keep you posted.

Pathways around the campus.
Intrigued by the variety and lushness of the huge corporate gardens, I talked to landscape architect Mark Brumbaugh, whose company Brumbaugh & Associates has been responsible for designing the grounds of Microsoft for years. Mark described how the design process has always been connected to the Northwest values: a love for nature and outdoor recreation. In the latest project, a new building area of 43 acres was designed to reflect the four regional habitat landscape types: coast, mountains, forests and meadows, each of them with their own distinct identity. Using local materials and plants suited to each habitat (not all of which are native), they were designed to provide interest during all 12 months of the year at the same time being reasonably easy to maintain.

Microsoft's Senior facilities manager Michael Impala generously also took time to meet me, revealing some fascinating details about landscaping on this giant scale. For example, a full-sized soccer field, basketball, bocce and sand volley ball courts and an underground garage with 192.000 square foot green roof and a forest trail for running are all included in the design, all imposing their own requirements for planting and maintenance. Also, security of the employees who use the grounds has to be taken into account. Using hardy native plants is not only a matter of design, but it is also a way to keep the grounds sustainable maintenance- and irrigationwise. Despite its rainy reputation, over 90 percent of the precipitation in Seattle area falls between September and April, making special water-saving computerized irrigation systems necessary during the dry summer months.

Wandering through the huge grounds of Microsoft, I was impressed both by the variety of detail and by their excellent connection with the surrounding landscape. Despite their scale, they felt at times almost intimate, an effect achieved mainly by skillful selection of vegetation. Huge grasses rustled besides curving paths and meadow like planting areas, with benches and seats scattered along the trail for moments of discussion or reflection of thought. Being a busy Tuesday morning, no-one was using the sports grounds, but many were enjoying their lattes by the dining area with water features providing a pleasant background for discussions.

Deriving from the long tradition of university campuses in the US, where beautiful landscaping has for long been used to attract and retain students and staff (two wonderful examples of which are the campuses of Stanford and Berkeley), the Microsoft campus is built on a similar theme. Overall, it is an admirable display of the software giant's commitment to provide a great working environment for its employees.
Thank you, Mark and Michael, for taking time to tell about the Microsoft grounds!
