Managing large variations in herbage production, resulting from highly variable seasonal rainfall, provides a major challenge for the sustainable management of Astrebla (Mitchell grass) grasslands in Australia. A grazing study with sheep was conducted between 1984 and 2010 on an Astrebla grassland in northern Queensland to describe the effects of a range of levels of utilisation of the herbage at the end of the summer growing season (April–May in northern Australia) on the sustainability of these grasslands. In unreplicated paddocks, sheep numbers were adjusted annually to achieve 0, 10, 20, 30, 50 and 80% utilisation of the herbage mass at the end of the summer over the ensuing 12 months. Higher levels of utilisation reduced both total and Astrebla spp. herbage mass because of the effects of higher utilisation on Astrebla spp. and this effect was accentuated by drought. The tussock density of Astrebla spp. varied widely among years but with few treatment differences until 2005 when density was reduced at the 50% level of utilisation. A major change in density resulted from a large recruitment of Astrebla spp. in 1989 that influenced its density for the remainder of the study. Basal area of the tussocks fluctuated among years, with increases due to rainfall and decreases during droughts. Seasonal rainfall was more influential than level of utilisation in changes to the basal area of perennial grasses. Drought resulted in the death of Astrebla spp. tussocks and this effect was accentuated at higher levels of utilisation. A series of three grazing exclosures were used to examine the recovery of the density and basal area of Astrebla spp. after it had been reduced by 80% utilisation over the preceding 9 years. This recovery study indicated that, although grazing exclusion was useful in the recovery of Astrebla spp., above-average rainfall was the major factor driving increases in the basal area of perennial grasses. Spring values of the Southern Oscillation Index and associated rainfall probabilities were considered to have potential for understanding the dynamics of Astrebla spp. It was concluded that Astrebla grassland remained sustainable after 26 years when grazed at up to 30% utilisation, while, at 50% utilisation, they became unsustainable after 20 years. Results from this study emphasised the need to maintain the population of Astrebla spp. tussocks.

The occurrence of interstitial species in Astrebla grasslands in Australia are influenced by grazing and seasonal rainfall but the interactions of these two influences are complex. This paper describes three studies aimed at determining and explaining the changes in plant species richness and abundance of the interstitial species in a long-term sheep utilisation experiment in an Astrebla grassland in northern Queensland. In the first study, increasing utilisation increased the frequency of Dactyloctenium radulans (Button grass) and Brachyachne convergens (Downs couch) and reduced that of Streptoglossa adscendens (Mint bush). In the second study, seasonal rainfall variation between 1984 and 2009 resulted in large annual differences in the size of the seed banks of many species, but increasing utilisation consistently reduced the seed bank of species such as Astrebla spp. and S. adscendens and increased that of species such as B. convergens, D. radulans, Amaranthus mitchellii (Boggabri) and Boerhavia sp. (Tar vine). In the third study, the highest species richness occurred at the lightest utilisation because of the presence of a range of palatable forbs, especially legumes. Species richness was reduced as utilisation increased. Species richness in the grazing exclosure was low and similar to that at the heaviest utilisation where there was a reduction in the presence of palatable forb species. The pattern of highest species richness at the lightest grazing treatment was maintained across three sampling times, even with different amounts of seasonal rainfall, but there was a large yearly variation in both the density and frequency of many species. It was concluded that the maintenance of highest species richness at the lightest utilisation was not aligned with other data from this grazing experiment which indicated that the maximum sustainable wool production occurred at moderate utilisation.

In just one of the many extraordinary moments during the spectacular Opening Ceremony of the 2012 London Olympic Games, thirty Mary Poppinses floated into the stadium on their umbrellas to battle a 40 foot-long inflatable Lord Voldemort. This multi-million pound extravaganza was telecast to a global audience of over one billion people, highlighting in an extremely effective manner the grandeur and eccentricities of the host nation, and featuring uniquely British icons such as Mr Bean, James Bond, The Beatles and Harry Potter, as well as those quintessential icons of Englishness, the Royal Family, double-decker red buses and the National Health Service.

For Independent Finland. The Military Committee 1915–1918 In the course of the First World War, several organizations were founded with the purpose of making Finland independent or, at least, restoring her autonomous status. The Military Committee was the most significant active independence organization in Finland in the First World War, in addition to the activist student movement, i.e., the Jaeger Movement. The Military Committee was an organization founded in 1915 by officers who had attended the Hamina Cadet School, with the goal of creating a national army for a liberation war against the Russian troops. It was believed that the liberation war should succeed only with the help of the German Army. With the situation in society continually tensing up in the autumn 1917, the Military Committee also had to figure on the possibility of a Civil War. The activities of the Military Committee started in the early part of 1915 when they were still small-scale, but they gained significant momentum after the Russian Revolution in March 1917. In January 1918, the Military Committee formed the general staff for the White Army, the Senate’s troops. The independence-related activities of the Hamina cadets in the years of the First World War were more extensive and multifaceted than has been believed heretofore. The work of the Military Committee was divided into preparations for a liberation war in Finland, on one hand, and in Stockholm and Berlin, on the other hand. In Finland, the Military Committee took part in intelligence gathering for Germany and in supporting the recruiting Jaegers, and later in founding the civil guard organization, in solving the law and order authorities issue, and finally in selecting the Commander-in-Chief for the Senate’s troops. The member of the Military Committee, especially Captain Hannes Ignatius of the Cavalry contributed greatly to the drafting of the independence activists’ national action plan in Stockholm in May 1917. This plan preceded the formation of the civil guard organization. The Military Committee’s role in founding the civil guards was initially minor, but in the fall of 1917, the Military Committee started to finance the activities of the civil guards, named several former officers as commanders of the civil guards and finally overtook the entire civil guard movement. In Stockholm and Berlin, the representatives of the Military Committee were in active contact with both the high command of the German Army and with the representatives of the Swedish Army. Colonel Nikolai Mexmontan, who was a representative of the Military Committee, collaborated with Swedish officers and Jaeger officers in Stockholm in coming up with comprehensive and detailed plans for starting the Liberation War. Under Mexmontan’s leadership, there were serious negotiations to enter into a confederation with Germany. Lieutenant Colonel Wilhelm Thesleff, on the other hand, became the commander of the Jaeger Battalion 27. The influence and importance of the Military Committee came to the forefront in independent and conflict-torn Finland. The Military Committee became a Senate committee on the 7th of January 1918, with its chairman, for all practical purposes, as the Commander-in-Chief in an eventual war. Lieutenant General Claes Charpentier was the chairman of the Military Committee from mid-December 1917 onwards, but on the 15th of January 1918 he had to resign in favour of Lieutenant General Gustaf Mannerheim. Soon after that, Mannerheim got an order from the chairman of the Senate P. E. Svinhufvud to organize and assume the leadership of the law and order authorities. The chairman of the Military Committee became the Commander-in-Chief of the Senate troops in January 1918, and the Military Committee became the Commander-in-Chief’s general staff. The Military Committee had turned from a clandestine organization into the first general staff of the independent Finnish Army.
