A Rhamnus cathartica sighting in Killarney, Co Kerry? Turns out to be spindle!


Euonymus europaeus
Quite unexpectedly after my first morning botanizing in Killarney National Park I found, I believe, a nice specimen of common buckthorn [update: though.it turned out to be spindle (Euonymus europaeus), see below].  I found it right beside Mucross Abbey, a deserted monastic site in the national park.  It is known to be a calcicole species here (though it can be found on quite acidic soils in the US Midwest) so it is not surprising to find it in the limestone region of the park..
Euonymus europaeus

The species is an old friend.  Because it is a problematic species from a management perspective in the US, it is hunted down and controlled (cut, poisoned and burned!) when it interferes with conservation plans for a preserve.  And rightly so, I would say.  However, it is attractive, hardy, and a great success in the US - my relationship with it has always been that of pupil and master, or perhaps merely envy on my part.  For whatever reason, I have spent the better part of a decade interested in this shrub, though truthfully we still don't know enough about it.

Those of you who know this plant well take a look a see if you agree with me that it is, in fact, buckthorn.  If it is not, I will be back in the field in the coming days.  The finely toothed leaves are almost opposite.  Though it is not fruiting yet the fruits are developing in clusters.  Also the bark is much grayer than I am used to seeing in the Midwest.

UPDATE 22nd July 2012: - There were enough differences between this specimen and R cathartica I am used to seeing in the midwest that I spend a little time working on it with some keys later that day.  With the assistance of old pals Helena Twomey and Bill Quirke (of Conservation Services) it was a much better fit for  spindle (Euonymus europaeus).  Fortunately I found buckthorn a few days later in Co Mayo.

Rhamnus cathartica in Ireland

A very helpful note from Dr Daniel Kelly from the Botany Department at Trinity College on the location of R cathartica in Ireland.  This otherwise very attractive shrub/small tree is a management nuisance in the Midwest, especially prevalent in the Chicago Wilderness region.


Dr Kelly reports from the 'Flora of Connemara & the Burren': "Woods, scrub, river-banks, rocky lake-shores and the margins of turloughs. Locally frequent on the limestone; very rare elsewhere..." "... Very frequent ... from near Oughterard to 3 km N. of Galway ... Locally abundant by the S. shore of L. Mask. Sparingly on the shore of L. Corrib in the grounds of Ashford Castle, and frequent on several of the islands."

It will be nice to see this plant in circumstances that do not provoke indignation and death-threats!

Ireland 2012 in preparation for Ireland 2013


Many of the posts for the coming weeks will be about the National Parks and environs of Killarney, Connemara, and Wicklow.  I will travelling there in preparation for a study abroad trip scheduled there for DePaul students.  The program is co-directed by me and Randall Honold, a colleague at DePaul.  Randall's training is in philosophy, mine is in ecology: what could possibly go wrong. For more information on the trip see here.

I will be rereading and commenting on Robert Lloyd Praeger’s book The Way That I Went as I go.  Another book that will travel the circuit with me is Tim Robinson’s Connemara: A Little Gaelic Kingdom (Penguin Ireland, 2011), the third in his trilogy of Connemara books.

Spat out of Nature by Nature: Konrad Lorenz and the Rise and Fall of Ethology


Jackdaws (Corvus monedula), widespread crows throughout Ireland, make delightful pets.  A school friend of mine in Dublin, Sean Farrell, kept one for a few months back in the late 1970s when we were both in our early teens.  The bird had broken its wing and Sean nursed it back to health.  The jackdaw was a noisy fellow and had his species' penchant for shiny things.  Sometime later I was happy to read that Konrad Lorenz (1903-1989), the Austrian ethologist, published a behavioral study of a colony of Jackdaws that he maintained and included an account of the birds in his charming book King Solomon’s Ring.  King Solomon’s Ring, (the title is taken from the legend that Solomon had a ring that allowed him to talk to the animals), was a popularization of the emerging science of ethology, that is, the biological study of behaviour, and was perhaps the first book that confirmed to me that there was a to make a living out of what I happened to like to do.

I progressed from the lighter but nonetheless delightful accounts of animal behavior in King Solomon’s Ring and in Niko Tinbergen’s Curious Naturalists to the greater heft of Lorenz’s classic On Aggression (1966) which I read as a zoology undergrad at University College Dublin in the 1980s.  In this book, published later in his career when he was in his sixties, Lorenz shared his mature analysis of how insights from the study of the instinctual behaviour of animals can be helpful in thinking about the human condition.  As we shall see, as a good Darwinian he regarded human conduct as revealing much about our essentially animal nature, but unlike other animals we posses, he argued, a characteristic of being able to overcome this legacy.  In fact, he deemed it critical to our species survival that we simultaneously evaluate the evolution of aggressiveness in a clear-headed way while we find cultural solutions to discharging these unavoidable tendencies in a harmless way.  More harmless than war, that is.  Lorenz had lived through a war and he was committed to helping humanity avoid another one on that scale.

Before looking at the details of Lorenz’s analysis of human nature (in the post to follow this one) a word or two about the science of ethology which emerged as biological subdiscipline in the 20th Century under Lorenz’s and Tinbergen’s influence.  Together with Karl von Frisch, who worked out the details on the so-called “waggle-dance” of honeybees that allowed the hive to share information on the location of a food source, Lorenz and Tinbergen shared the Nobel Prize (in medicine) in 1973.  A primary task of ethology was to place questions about the behaviour of animals in an evolutionary context.  How does the behavior function to increase the success of the animal; what are the triggers for the expression of that behavior, how does the behavior develop in the life of that individual; and, finally, what was the pattern in the evolutionary development of the behavior?[1],[2]  Some regarded it as a strength of the discipline that it simultaneously asked questions about the adaptive nature of the behavior, the mechanism by which the behavior is displayed, and how functions in the ecology of the organism. Critics, however, saw in this the danger that teleological thinking could creep into the analysis: the assumption that behavior developed to the point of ever increasing perfection as the behavior reached a preordained goal.

Apocalypse and Utopia in Equal Measure


In an essay entitled Mechanism of Utopia Emil Cioran (1911-1995), the notoriously pessimistic Romanian philosopher, declared his surprise that “riots do not break out every day: massacres, unspeakable carnage, a doomsday chaos.”[1]  It is not, he concluded, that our hatred for each other is insufficient; rather, we are saved by the being too mediocre to fully act upon our mutual odium.  The balance of these opposing propensities permits us to soldier on.  More affably, one might just as well wonder why peace and kindredness are not more stable and enduring.  Certainly we profess to desiring them.  Sunnier times do not prevail, one suspects, not merely because our baser natures assert themselves and we disincline to tame them, but because the better and worse aspects of our natures are blended through the human mix, rather like the fruit in a Christmas pudding.  A sultana in every forkful; a little bit of anger, or condescension, or pride in every charitable act.

Utopian visions are born of destitution, in the depths of which one feels there is a better world just within reach.  And when this destitution is at its most profound, the utopian wants everything to change.  “Air annoys you.” Cioran wrote, “let it be transformed.”  The utopian imagines that all can, in fact, be changed, even herself!  That is, her view is that human nature is such that the rages of our bruter natures can be quelled.  Apocalyptic visions are utopias without the swaggering self-confidence in the unbounded mutability of our natures.  The Apocalyptic looks at her derelict conditions and sees only ruination.   

Ecological utopias have two complementary dimensions: one orients towards a better place, the other towards a better time.  That better place may be one that is currently blasted, but now re-imagined by ecological and social engineers (the sustainable city), or alternatively, that better place can turn away from the contemporary landscape, desiring to build elsewhere: the rural commune (the sustainable subdivision), or the planetary escape (Mars Now!).  Utopias models themselves upon a different age, former times or an imagined future.  In this sense utopia (without place) can also be utemporalis (without a time).  The “without” in both terms represent the absence of this particular here and now – utopia imagining a place that is not here, utemporalis imagine a time that has passed or is yet to come.  Ecological utopias can be restorative, a hankering after a historical Gold Age (for ecologists it will not be the world of the Athenian citizen rather the world of the plains hunter).  Alternatively, utopia it can be directed towards a bright new future, a non-analogue future where the principles of sound design conceive a world that has never been seen before.

If Leopold’s Land Ethic was going to work would we know it by now?

A few months ago I wrote a fairly critical account of Aldo Leopold’s Land Ethic.  To restate my contention from my original post: If the land ethic was going to work as formulated in the 1940s we’d probably know about it by now.  

Eric Daryl Meyer recently responded with some comments on my post and with some additional comments on Leopold’s essay (see here). I'll respond to Eric at greater length soon:  perhaps one of the metrics of the significance of Leopold's essay is that, even when one thinks one knows it, it is nevertheless worth revisiting before one writes about it in detail.  But for now a few initial comments.

Eric wrote that I overstated the disjunction that Leopold makes between philosophical and ecological ethics.  This may be the case – Leopold’s writing is a little muddy on this point.  That is, he claims that it’s the “extension” of ethics that has so far only been studied by philosophers. Therefore an ecological account of this extension is what’s needed – a geological accretion of sorts.  Therefore, Leopold was not taking on ethics in its entirety – just the more focused question of how one gives to the land that which we already, in theory, grant to one another, that is, ethical consideration.  However, it is pretty clear that in attempting to reconcile a philosophical definition of ethics with an ecological one he splits the difference in favor of the ecological.  To be clear, I don’t think that Leopold is making philosophy and ecology disjunct: he is rather conflating them and saying that if we solve, so to speak, the equation for the “x” of evolutionary ecology, we also get the “y” of philosophical ethics. That is for Leopold x=y.  With this the resources of philosophy, which might be a very useful partner in developing the land ethic, get brushed aside.

Now, it may simply be the case that Leopold has no particular interest in the deliberations of let’s say the past couple of millennia of philosophy on the question of ethics.  That’s fine – pessimism on the question of how philosophy will help us in the matter of an ethical extension to the land community may be reasonable. But it doesn’t seem to me that we get an awful lot from Leopold's speculation about social evolution or from Eltonian ecology either.  (That being said, he does anticipate several issues that became important in ecology only decades after the land ethic.) 

It’s with all of this is mind that I said we need to save the Land Ethic from Leopold’s particular account of it.  In my original post I noted that there has been a lot of work on the land ethic in the past decades –work that often supplements precisely what Leopold sets aside.  I had invited my readers to set this aside for the time being so that we could get back to Leopold’s essay in our efforts to finally get past it.  Perhaps this was not an especially helpful suggestion.  That being said, in some ways it seems to me that this is what Eric does in his short but interesting post.  I say this not to be agreeable, but because I think the approach, Eric’s approach, hints at some paths forward. 

An example: Eric helps out Leopold by saying that he didn’t really mean “to extend” ethics but rather that he wanted to put philosophical ethical considerations back in their deeper ecological context.  Now to maintain this one has to discount some of what Leopold says – he seemed to mean extend in a pretty concrete way.  In fact, helpful diagrams of the development of ethics depicting the Leopoldian extension abound. Both Leopold and his interpreters see it in these terms.  Therefore Eric’s rereading of this get’s beyond Leopold in a fairly provocative manner.

Eric says that once we put ethics in their ecological context then we may get “human beings to recognize their already-situatedness in relations to living and non-living beings…” That is, we will have a new understanding of ourselves. Perhaps; certainly it seems necessary.  But as Eric notes (concurring with me) we are left with no idea about the means by which this comes about. To push for a “framework in which it is feasible for people to…self identify as citizens…of the ecological community…” is simply to hope for the same think that Leopold hoped for.  I regard this as useful, however, because Eric concludes as I do that one needs to clear away, or at the very least reinterpret, a lot of the work in Leopold’s essay to get to its useful core.  In other words the land ethic needs to be rescued from Leopold’s treatment of it.

[An essay by William Jordan II with contributions of the "values group" on the value theory that I alluded to in the original post will appear in Environmental Ethics later this year.  Also, I briefly, very briefly, comment on Leopold and the Balance of Nature in this recent post at 3Quarksdaily]
