[MAIPC] Impacts to tourism from invasive species

My quick search yielded much less than I imagined. Most are probably already familiar with the Pimentel et al. studies of costs from the 1999/2000 and 2005 papers. What I didn’t know, or at least forgot, was that there was very little information about tourism impacts in those. In fact the only thing I can find in those is the following case:

In Florida, exotic aquatic plants, such as hydrilla (Hydrilla verticillata), water hyacinth (Eichhornia crassipes), and water lettuce (Pistia straiotes), are altering fish and other aquatic animal species, choking waterways, altering nutrient cycles, and reducing recreational use of rivers and lakes. Active control measures of the aquatic weeds have become necessary (OTA 1993). For instance, Florida spends about $14.5 million each year on hydrilla control (Center et al. 1997). Nevertheless, hydrilla infestations in just 2 Florida lakes have caused an estimated $10 million in recreational losses in the lakes annually (Center et al. 1997).

Center at al refers to: Center TD, Frank JH, Dray FA. 1997. Biological control. Pages 245-266 in Simberloff D, Schmitz DC, Brown TC, eds. Strangers in Paradise. Washington, DC: Island Press.

I assume there is more out there.

Subject: [MAIPC] Impacts to tourism from invasive species

Good morning!

This may have been a subject recently posted about on the MAIPC listserve (as it seems slightly familiar to me…), but I was wondering if anyone has information on ball-park estimates of economic costs specifically to tourism that can be derived from the harmful impacts posed by invasive species?
